The MCP1700 is capable of delivering 250 mA with
only 178 mV of input to output voltage differential
(VOUT = 2.8V). The output voltage tolerance of the
MCP1700 is typically ±0.4% at +25°C and ±3%
maximum over the operating junction temperature
range of -40°C to +125°C.
Output voltages available for the MCP1700 range from
1.2V to 5.0V. The LDO output is stable when using only
1 µF output capacitance. Ceramic, tantalum or
aluminum electrolytic capacitors can all be used for
input and output. Overcurrent limit and overtemperature
shutdown provide a robust solution for any application.
Package options include SOT-23, SOT-89, TO-92 and
2x2 DFN-6.

The minimum VIN must meet two conditions: VIN  2.3V and VIN  VR + 3.0%  VDROPOUT.
VR is the nominal regulator output voltage. For example: VR = 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.0V, 5.0V. The
input voltage VIN = VR + 1.0V; IOUT = 100 µA.
TCVOUT = (VOUT-HIGH - VOUT-LOW) *106 / (VR * Temperature), VOUT-HIGH = highest voltage measured over the
temperature range. VOUT-LOW = lowest voltage measured over the temperature range.
Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output
voltage due to heating effects are determined using thermal regulation specification TCVOUT.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured
value with a VR + 1V differential applied.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction
temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the maximum allowable power
dissipation will cause the device operating junction temperature to exceed the maximum 150°C rating. Sustained
junction temperatures above 150°C can impact the device reliability.
The junction temperature is approximated by soaking the device under test at an ambient temperature equal to the
desired Junction temperature. The test time is small enough such that the rise in the Junction temperature over the
ambient temperature is not significant.

Exposed Thermal Pad (EP)
There is an internal electrical connection between the
Exposed Thermal Pad (EP) and the GND pin; they
must be connected to the same potential on the Printed

Connect VOUT to the positive side of the load and the
positive terminal of the output capacitor. The positive
side of the output capacitor should be physically
located as close to the LDO VOUT pin as is practical.
The current flowing out of this pin is equal to the DC

3.3
Unregulated Input Voltage Pin
(VIN)
Connect VIN to the input unregulated source voltage.
As with all low dropout linear regulators, low source
impedance is necessary for the stable operation of the
LDO. The amount of capacitance required to ensure
low source impedance will depend on the proximity of
the input source capacitors or battery type. For most
applications, 1 µF of capacitance will ensure stable
operation of the LDO circuit. For applications that have
load currents below 100 mA, the input capacitance
requirement can be lowered. The type of capacitor
used can be ceramic, tantalum or aluminum
electrolytic. The low ESR characteristics of the ceramic
will yield better noise and PSRR performance at high
frequency.

DETAILED DESCRIPTION
4.1
Output Regulation
4.3
A portion of the LDO output voltage is fed back to the
internal error amplifier and compared with the precision
internal bandgap reference. The error amplifier output
will adjust the amount of current that flows through the
P-Channel pass transistor, thus regulating the output
voltage to the desired value. Any changes in input
voltage or output current will cause the error amplifier
to respond and adjust the output voltage to the target
voltage (refer to Figure 4-1).
4.2
Overtemperature
The internal power dissipation within the LDO is a
function of input-to-output voltage differential and load
current. If the power dissipation within the LDO is
excessive, the internal junction temperature will rise
above the typical shutdown threshold of 140°C. At that
point, the LDO will shut down and begin to cool to the
typical turn-on junction temperature of 130°C. If the
power dissipation is low enough, the device will
continue to cool and operate normally. If the power
dissipation remains high, the thermal shutdown
protection circuitry will again turn off the LDO,
protecting it from catastrophic failure.
Overcurrent
The MCP1700 internal circuitry monitors the amount of
current flowing through the P-Channel pass transistor.
In the event of a short circuit or excessive output
current, the MCP1700 will turn off the P-Channel
device for a short period, after which the LDO will
attempt to restart. If the excessive current remains, the
cycle will repeat itself.

FUNCTIONAL DESCRIPTION
The MCP1700 CMOS low dropout linear regulator is
intended for applications that need the lowest current
consumption while maintaining output voltage
regulation. The operating continuous load of the
MCP1700 ranges from 0 mA to 250 mA (VR  2.5V).
The input operating voltage ranges from 2.3V to 6.0V,
making it capable of operating from two, three or four
alkaline cells or a single Li-Ion cell battery input.
5.1
Input
The input of the MCP1700 is connected to the source
of the P-Channel PMOS pass transistor. As with all
LDO circuits, a relatively low source impedance (10)
is needed to prevent the input impedance from causing
the LDO to become unstable. The size and type of the
required capacitor depend heavily on the input source
type (battery, power supply) and the output current
range of the application. For most applications (up to
100 mA), a 1 µF ceramic capacitor will be sufficient to
ensure circuit stability. Larger values can be used to
improve circuit AC performance.
5.2
Output
The maximum rated continuous output current for the
MCP1700 is 250 mA (VR  2.5V). For applications
where VR < 2.5V, the maximum output current is
200 mA.
A minimum output capacitance of 1.0 µF is required for
small signal stability in applications that have up to
250 mA output current capability. The capacitor type
can be ceramic, tantalum or aluminum electrolytic. The
ESR range on the output capacitor can range from 0
to 2.0.
5.3
Output Rise time
When powering up the internal reference output, the
typical output rise time of 500 µs is controlled to
prevent overshoot of the output voltage.

MCP1700
VOUT
1.8V
The maximum continuous operating junction
temperature specified for the MCP1700 is +125°C. To
estimate the internal junction temperature of the
MCP1700, the total internal power dissipation is
multiplied by the thermal resistance from junction to
ambient (RJA). The thermal resistance from junction to
ambient for the SOT-23 pin package is estimated at
230°C/W.
POWER DISSIPATION
The internal power dissipation of the MCP1700 is a
function of input voltage, output voltage and output
current. The power dissipation resulting from the
quiescent current draw is so low it is insignificant
(1.6 µA x VIN). The following equation can be used to
calculate the internal power dissipation of the LDO.

can be used to determine the maximum internal power
dissipation of the package.

Voltage Regulator
Internal power dissipation, junction temperature rise,
junction temperature and maximum power dissipation
are calculated in the following example. The power
dissipation resulting from ground current is small
enough to be neglected.
6.3.1
POWER DISSIPATION EXAMPLE
Package
TJ(RISE) = PTOTAL x RJA
TJ(RISE) = 218.1 milli-Watts x 230.0°C/Watt
TJ(RISE) = 50.2°C
Junction Temperature Estimate
To estimate the internal junction temperature, the
calculated temperature rise is added to the ambient or
offset temperature. For this example, the worst-case
junction temperature is estimated below.
TJ = TJ(RISE) + TA(MAX)
TJ = 90.2°C
Maximum Package Power Dissipation at +40°C
Ambient Temperature
2x2 DFN-6 (91°C/Watt = RJA)

PD(MAX) = 934 milli-Watts

Package Type = SOT-23
PD(MAX) = (125°C - 40°C) / 230°C/W

PD(MAX) = 369.6 milli-Watts
VIN = 2.3V to 3.2V
LDO Output Voltages and Currents
VOUT = 1.8V
IOUT = 150 mA
Maximum Ambient Temperature
TA(MAX) = +40°C
SOT-89 (52°C/Watt = RJA)
PD(MAX) = (125°C - 40°C) / 52°C/W
PD(MAX) = 1.635 Watts
TO-92 (131.9°C/Watt = RJA)
PD(MAX) = (125°C - 40°C) / 131.9°C/W
PD(MAX) = 644 milli-Watts
Internal Power Dissipation
Internal Power dissipation is the product of the LDO
output current times the voltage across the LDO
(VIN to VOUT).
PLDO(MAX) = (VIN(MAX) - VOUT(MIN)) x IOUT(MAX)
PLDO = (3.2V - (0.97 x 1.8V)) x 150 mA
PLDO = 218.1 milli-Watts
Device Junction Temperature Rise
The internal junction temperature rise is a function of
internal power dissipation and the thermal resistance
from junction to ambient for the application. The thermal
resistance from junction to ambient (RJA) is derived
from an EIA/JEDEC® standard for measuring thermal
resistance for small surface mount packages. The EIA/
JEDEC specification is JESD51-7, “High Effective
Thermal Conductivity Test Board for Leaded Surface
Mount Packages”. The standard describes the test
method and board specifications for measuring the
thermal resistance from junction to ambient. The actual
thermal resistance for a particular application can vary
depending on many factors, such as copper area and
thickness. Refer to AN792, “A Method to Determine
How Much Power a SOT-23 Can Dissipate in an
Application” (DS00792), for more information regarding
this subject.

Voltage Reference
The MCP1700 can be used not only as a regulator, but
also as a low quiescent current voltage reference. In
many microcontroller applications, the initial accuracy
of the reference can be calibrated using production test
equipment or by using a ratio measurement. When the
initial accuracy is calibrated, the thermal stability and
line regulation tolerance are the only errors introduced
by the MCP1700 LDO. The low cost, low quiescent
current and small ceramic output capacitor are all
advantages when using the MCP1700 as a voltage
reference.

Using the MCP1700 as a
Pulsed Load Applications
For some applications, there are pulsed load current
events that may exceed the specified 250 mA
maximum specification of the MCP1700. The internal
current limit of the MCP1700 will prevent high peak
load demands from causing non-recoverable damage.
The 250 mA rating is a maximum average continuous
rating. As long as the average current does not exceed
250 mA, pulsed higher load currents can be applied to
the MCP1700. The typical current limit for the
MCP1700 is 550 mA (TA + 25°C).

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
