LM4132, LM4132-Q1 SOT-23 Precision Low Dropout Voltage Reference
1 Features
3 Description
•
•
The LM4132 family of precision voltage references
performs comparable to the best laser-trimmed
bipolar references, but in cost-effective CMOS
technology. The key to this breakthrough is the use of
EEPROM registers for correction of curvature,
temperature coefficient (tempco), and accuracy on a
CMOS band-gap architecture allowing package-level
programming to overcome assembly shift. The shifts
in voltage accuracy and tempco during assembly of
die into plastic packages limit the accuracy of
references trimmed with laser techniques.

VIN Range of VREF + 400 mV to 5.5 V at 10 mA
Stable With Low-ESR Ceramic Capacitors
Unlike other LDO references, the LM4132 can deliver
up to 20 mA and does not require an output capacitor
or buffer amplifier. These advantages along with the
SOT-23 packaging are important for space-critical
applications.
Series references provide lower power consumption
than shunt references, because they do not have to
idle the maximum possible load current under no-load
conditions. This advantage, the low quiescent current
(60 µA), and the low dropout voltage (400 mV) make
the LM4132 ideal for battery-powered solutions.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX
(maximum junction temperature), RθJA (junction to ambient thermal resistance) and TA (ambient temperature). The maximum power
dissipation at any temperature is: PDissMAX = (TJMAX – TA) / RθJA up to the value listed in theAbsolute Maximum Ratings. RθJA for SOT-23
is 164.1°C/W, TJMAX = 125°C.

Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control.
Typical numbers are at 25°C and represent the most likely parametric norm.
Long-term stability is VREF at 25°C measured during 1000 hrs.
Thermal hysteresis is defined as the change in 25°C output voltage before and after cycling the device from (–40°C to 125°C).
Dropout voltage is defined as the minimum input to output differential at which the output voltage drops by 0.5% below the value
measured with a 5-V input.

7 Detailed Description
7.1 Overview
The LM4132 device is a precision band-gap voltage reference available in 6 different voltages with 20-mA
current source capability. This series reference can operate with input voltages from VREF + 400 mV to 5.5 V
while consuming 60-µA (typical) supply current. In shutdown mode, current drops to 3 µA (typical). The LM4132
is available in five grades from A and E.
The best grade devices (A) have an initial accuracy of 0.05% with a specified tempco of 10 ppm/°C from –40°C
to 125°C. The grade devices (E) have an initial accuracy of 0.5% with specified tempco of 30 ppm/°C from –40°C
to 125°C.

7.3 Feature Description
The LM4132 can be remotely operated by applying an EN voltage between 65% of VIN, and VIN. The LM4312
can be remotely disabled by applying an EN voltage between 0 V to 35% of VIN. The EN pin can also be
strapped to VIN, so VREF is active when VIN is applied.
7.3.1 Short Circuited Output
The LM4132 features indefinite short-circuit protection. This protection limits the output current to 75 mA when
the output is shorted to ground.
7.3.2 Turnon Time
Turnon time is defined as the time taken for the output voltage to rise to 90% of the preset value. The turnon time
depends on the load. The turnon time is typically 33.2 µs when driving a 1-µF load and 78.8 µs when driving a
10-µF load. Some users may experience an extended turnon time (up to 10 ms) under brownout conditions and
low temperatures (–40°C).

7.3.3 Thermal Hysteresis
Thermal hysteresis is defined as the change in output voltage at 25ºC after some deviation from 25ºC. This is to
say that thermal hysteresis is the difference in output voltage between two points in a given temperature profile.
An illustrative temperature profile is shown in Figure 47.

8 Applications and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LM4132 family of precision voltage references can deliver up to 20 mA without an output capacitor or buffer
amplifier. The LM4132 is ideal for battery-powered solutions, with a low quiescent current of 60 µA, and a low
dropout voltage of 400 mV. The LM4132 enters the shutdown mode (3 µA, typical) when EN is 0 V.

8.2.1.1 Design Requirements
For this design example, use the parameters listed as the input parameters.
• VIN > VREF + 400 mV (ILOAD ≤ 10 mA)
• ILOAD ≤ 20 mA
• The LM4132 is enabled when 65%VIN< VEN ≤ VIN. VEN cannot be greater than VIN; otherwise, the device does
not operate correctly.
• The devices is disabled when 0 V ≤ VEN ≤ 35% VIN.
8.2.1.2 Detailed Design Procedure
The foundation of any voltage reference is the band-gap circuit. While the reference in the LM4132 is developed
from the gate-source voltage of transistors in the device, principles of the band-gap circuit are easily understood
using a bipolar example. For a detailed analysis of the bipolar band-gap circuit, refer to AN-56 LM113 1.2V
Reference (SNVA514).
8.2.1.2.1 Supply and Enable Voltages
To ensure proper operation, VEN and VIN must be within a specified range. An acceptable range of input voltages
is calculated by Equation 2:
VIN > VREF + 400 mV (ILOAD ≤ 10 mA)
(2)
The EN pin uses an internal pullup current source (IPULLUP ≊ 2 µA) that may be left floating or triggered by an
external source. If the device is not enabled by an external source, it may be connected to VIN. An acceptable
range of enable voltages is given by Figure 4. See Electrical Characteristics LM4132-1.8 (VOUT = 1.8 V) and
Figure 3 for more detail. The device does not operate correctly for VEN > VIN.

SNVS372G – AUGUST 2005 – REVISED OCTOBER 2016
Typical Applications (continued)
8.2.1.2.2 Component Selection
A small ceramic (X5R or X7R) capacitor on the input must be used to ensure stable operation. The value of CIN
must be sized according to the output capacitor value. The value of CIN must satisfy the relationship CIN ≥ COUT.
When no output capacitor is used, CIN must have a minimum value of 0.1 µF. Noise on the power-supply input
may affect the output noise. Larger input capacitor values (typically 4.7 µF to 22 µF) may help reduce noise on
the output and significantly reduce overshoot during start-up. Use of an additional optional bypass capacitor from
the input and ground may help further reduce noise on the output. With an input capacitor, the LM4132 drives
any combination of resistance and capacitance up to VREF / 20 mA and 10 µF, respectively.
The LM4132 is designed to operate with or without an output capacitor and is stable with capacitive loads up to
10 µF. Connecting a capacitor from the output and ground significantly improves the load transient response
when switching from a light load to a heavy load. The output capacitor must not be made arbitrarily large
because capacitor selection affects the turnon time as well as line and load transients.
While a variety of capacitor chemistry types may be used, it is typically advisable to use low equivalent series
resistance (ESR) ceramic capacitors. Such capacitors provide a low impedance to high frequency signals,
effectively bypassing them to ground. Bypass capacitors must be mounted close to the device. Mounting bypass
capacitors close to the device helps reduce the parasitic trace components thereby improving performance.
8.2.1.2.3 Temperature Coefficient
Temperature drift is defined as the maximum deviation in output voltage over the operating temperature range.
This deviation over temperature may be shown in Figure 48:
Temperature
Change in Output Voltage
Voltage
VREF_MAX
VREF_MIN
Temperature Range
Figure 48. VREF vs Temperature Profile
Temperature coefficient may be expressed analytically as Equation 3:
TD =
(VREF_MAX - VREF_MIN)
VREF x ΔT
x 106 ppm
where
•
•
•
•
•
•
TD = Temperature drift
VREF = Nominal preset output voltage
VREF_MIN = Minimum output voltage over operating temperature range
VREF_MAX = Maximum output voltage over operating temperature range
ΔT = Operating temperature range
The LM4132 features a low temperature drift of 10 ppm (maximum) to 30 ppm (maximum), depending on the
grade.
(3)
8.2.1.2.4 Long-Term Stability
Long-term stability refers to the fluctuation in output voltage over a long period of time (1000 hours). The LM4132
features a typical long-term stability of 50 ppm over 1000 hours. The measurements are made using 5 units of
each voltage option, at a nominal input voltage (5 V), with no load, at room temperature.

10 Layout
10.1 Layout Guidelines
The mechanical stress due to PCB mounting can cause the output voltage to shift from its initial value. The
center of a PCB generally has the highest mechanical and thermal expansion stress. Mounting the device near
the edges or the corners of the board where mechanical stress is at its minimum. References in SOT-23
packages are generally less prone to assembly stress than devices in small outline (SOIC) packages.
A mechanical isolation of the device by creating an island by cutting a U shape slot (U - SLOT) on the PCB while
mounting the device helps in reducing the impact of the PCB stresses on the output voltage of the reference.
This approach would also provide some thermal isolation from the rest of the circuit.
Figure 54 shows a recommended printed board layout for LM4132 along with an in-set diagram, which exhibits a
slot cut on three sides of the reference device.
Bypass capacitors must be mounted close to the device. Mounting bypass capacitors close to the device reduces
the parasitic trace components, thereby improving performance.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
