8 Detailed Description
8.1 Overview
The LM317L device is a 100-mA linear regulator with high voltage tolerance up to 35 V. The device has a
feedback voltage that is relative to the output instead of ground. This ungrounded design allows the LM317L
device to have superior line and load regulation. This design also allows the LM317L device to be used as a
current source or current sink using a single resistor. Any output voltage from 1.25 to 32 V can be obtained by
using two resistors. The bias current of the device, up to 2.5 mA, flows to the output; this current must be used
by the load or the feedback resistors. The power dissipation is the product of pass-element voltage and current,
which is calculated as shown in Equation 1.
PD = (VIN – VOUT) × IOUT
(1)
The application heat sink must be able to absorb the power calculated in Equation 1.
In addition to higher performance than fixed regulators, this regulator offers full overload protection, available
only in integrated circuits. Included on the chip are current-limiting and thermal-overload protection. All overloadprotection circuitry remains fully functional even when ADJUSTMENT is disconnected. Normally, no capacitors
are needed unless the device is situated far from the input filter capacitors, in which case an input bypass is
needed. An optional output capacitor can be added to improve transient response. ADJUSTMENT can be
bypassed to achieve very high ripple rejection, which is difficult to achieve with standard three-terminal
regulators.
In addition to replacing fixed regulators, the LM317L regulator is useful in a wide variety of other applications.
Since the regulator is floating and sees only the input-to-output differential voltage, supplies of several hundred
volts can be regulated as long as the maximum input-to-output differential is not exceeded. Its primary
application is that of a programmable output regulator, but by connecting a fixed resistor between ADJUSTMENT
and OUTPUT, this device can be used as a precision current regulator. Supplies with electronic shutdown can be
achieved by clamping ADJUSTMENT to ground, programming the output to 1.25 V, where most loads draw little
current.
The LM317LC device is characterized for operation over the virtual junction temperature range of 0°C to 125°C.
The LM317LI device is characterized for operation over the virtual junction temperature range of –40°C to 125°C.

8.3 Feature Description
8.3.1 NPN Darlington Output Drive
NPN Darlington output topology provides naturally low output impedance and an output capacitor is optional. To
support maximum current and lowest temperature, 2.5-V headroom is recommended (VI – VO).
8.3.2 Overload Block
Over-current and over-temperature shutdown protects the device against overload or damage from operating in
excessive heat.
8.3.3 Programmable Feedback
Op amp with 1.25-V offset input at the ADJUST pin provides easy output voltage or current (not both)
programming. For current regulation applications, a single resistor whose resistance value is 1.25 V / IOUT and
power rating is greater than (1.25 V)2 / R should be used. For voltage regulation applications, two resistors set
the output voltage. See Typical Application for a schematic and the resistor formula.
8.4 Device Functional Modes
8.4.1 Normal operation
The device OUTPUT pin will source current necessary to make OUTPUT pin 1.25 V greater than ADJUST
terminal to provide output regulation.
8.4.2 Operation With Low Input Voltage
The device requires up to 2.5-V headroom (VI – VO) to operate in regulation. With less headroom, the device
may drop out and OUTPUT voltage will be INPUT voltage minus drop out voltage.
8.4.3 Operation at Light Loads
The device passes its bias current to the OUTPUT pin. The load or feedback must consume this minimum
current for regulation or the output may be too high.
8.4.4 Operation In Self Protection
When an overload occurs the device will shut down Darlington NPN output stage or reduce the output current to
prevent device damage. The device will automatically reset from the overload. The output may be reduced or
alternate between on and off until the overload is removed.

9.2.2.1 Input Capacitor
An input capacitor is not required, but it is recommended, particularly if the regulator is not in close proximity to
the power-supply filter capacitors. A 0.1-µF ceramic or 1-µF tantalum provides sufficient bypassing for most
applications, especially when adjustment and output capacitors are used.
9.2.2.2 Output Capacitor
An output capacitor improves transient response, but it not needed for stability.

9.2.2.4 Adjustment Terminal Capacitor
The optional adjustment pin capacitor will improve ripple rejection by preventing the amplification of the ripple.
When capacitor is used and VOUT > 6 V, a protection diode from adjust to output is recommended.
9.2.2.5 Design Options and Parameters
Common Linear Regulator designs are concerned with the following parameters:
• Input voltage range
• Input capacitor range
• Output voltage
• Output current rating
• Output capacitor range
• Input short protection
• Stability
• Ripple rejection
9.2.2.6 Output Voltage
VO is calculated as shown in Equation 3.

VOUT = VREF ´ ç 1 + 2 ÷ + (IADJ ´ R2 )

(3)
Because IADJ typically is 50 µA, it is negligible in most applications.
9.2.2.7 Ripple Rejection
CADJ is used to improve ripple rejection; it prevents amplification of the ripple as the output voltage is adjusted
higher. If CADJ is used, it is best to include protection diodes.
9.2.2.8 Input Short Protection
If the input is shorted to ground during a fault condition, protection diodes provide measures to prevent the
possibility of external capacitors discharging through low-impedance paths in the IC. By providing low-impedance
discharge paths for CO and CADJ, respectively, D1 and D2 prevent the capacitors from discharging into the output
of the regulator.

10 Power Supply Recommendations
The LM317L device is designed to operate from an input voltage supply range between 2.5 V to 32 V greater
than the output voltage. If the device is more than six inches from the input filter capacitors, an input bypass
capacitor, 0.1 µF or greater, of any type is needed for stability.
11 Layout
11.1 Layout Guidelines
•
•
•
It is recommended that the input pin be bypassed to ground with a bypass-capacitor.
The optimum placement is closest to the VIN of the device and GND of the system. Care must be taken to
minimize the loop area formed by the bypass-capacitor connection, the VIN pin, and the GND pin of the
system.
For operation at full-rated load, it is recommended to use wide trace lengths to eliminate IR drop and heat
dissipation.

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.
