2 µA Low Dropout Positive Voltage Regulator
Features
General Description
• 2.0 µA Typical Quiescent Current
• Input Operating Voltage Range up to 10.0V
• Low Dropout Voltage:
The MCP1701 is a family of CMOS low dropout (LDO),
positive voltage regulators that can deliver up to
250 mA of current while consuming only 2.0 µA of
quiescent current (typical). The input operating range is
specified up to 10V, making it ideal for lithium-ion (one
or two cells), 9V alkaline and other two and three
primary cell battery-powered applications.
- 250 mV (typ.) @ 100 mA
- 500 mV (typ.) @ 200 mA
• High Output Current: 250 mA (V
= 5.0V)
OUT
• High-Accuracy Output Voltage: ±2% (max)
• Low Temperature Drift: ±100 ppm/°C (typ.)
• Excellent Line Regulation: 0.2%/V (typ.)
The MCP1701 is capable of delivering 250 mA with an
input-to-output voltage differential (dropout voltage) of
650 mV. The low dropout voltage extends the battery
operating lifetime. It also permits high currents in small
• Package Options: 3-Pin SOT-23A, 3-Pin SOT-89
packages when operated with minimum V – V

OUT
and 3-Pin TO-92
differentials.
• Short-Circuit Protection
The MCP1701 has a tight tolerance output voltage
regulation of ±0.5% (typical) and very good line regula-
tion at ±0.2%. The LDO output is stable when using
only 1 µF of output capacitance of either tantalum or
aluminum-electrolytic style capacitors. The MCP1701
LDO also incorporates short-circuit protection to
ensure maximum reliability.
• Standard Output Voltage Options:
- 1.8V, 2.5V, 3.0V, 3.3V, 5.0V
Applications
• Battery-Powered Devices
• Battery-Powered Alarm Circuits
• Smoke Detectors
Package options include the 3-Pin SOT-23A, 3-Pin
SOT-89 and 3-Pin TO-92.

1: VR is the nominal regulator output voltage. For example: VR = 1.8V, 2.5V, 3.3V, 4.0V, 5.0V.
The input voltage VIN = VR + 1.0V, IOUT = 40 mA.
2: TCVOUT = (VOUT-HIGH – VOUT-LOW) *106/(VR * ∆Temperature), VOUT-HIGH is equal to the highest voltage measured
over the temperature range, while VOUT-LOW is equal to the lowest voltage measured over the temperature range.
3: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing.

Regulator ground. Tie GND to the negative side of both
the output and the input capacitor. Only the LDO bias
current (2 µA, typical) flows out of this pin, as there is
no high current. The LDO output regulation is refer-
enced to this pin. Minimize voltage drops between this
pin and the negative side of the load.
Connect the input supply voltage and the positive side
of the input capacitor to V . Like all low dropout linear
IN
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

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 charac-
teristics of the ceramic will yield better noise and PSRR
performance at high frequencies. The current flow into
this pin is equal to the DC load current, plus the LDO
bias current (2 µA, typical).

DETAILED DESCRIPTION
A 1 µF input capacitor is recommended for most
applications when the input impedance is on the order
of 10Ω. Larger input capacitance may be required for
stability when operating from a battery input, or if there
is a large distance from the input source to the LDO.
When large values of output capacitance are used, the
input capacitance should be increased to prevent high
source impedance oscillations.
The MCP1701 is a low quiescent current, precision,
fixed-output voltage LDO. Unlike bipolar regulators,
the MCP1701 supply current does not increase
proportionally with load current.
4.1
Output Capacitor
A minimum of 1 µF output capacitor is required. The
output capacitor should have an effective series
resistance (esr) greater than 0.1Ω and less than 5Ω,
plus a resonant frequency above 1 MHz. Larger output
capacitors can be used to improve supply noise
rejection and transient response. Care should be taken
4.3
Overcurrent
The MCP1701 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 MCP1701 will act to limit the output current.

The amount of power dissipated internal to the LDO
linear regulator is the sum of the power dissipation
within the linear pass device (P-channel MOSFET) and

ence and error amplifier. The internal linear pass

multiply the maximum voltage differential by the
