MCP1701A

2 µA Low-Dropout Positive Voltage Regulator

Features

General Description

• 2.0 µA Typical Quiescent Current

The MCP1701A is a family of CMOS low-dropout,

positive voltage regulators that can deliver up to

250 mA of current while consuming only 2.0 µA of

quiescent current (typ.). 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.

• Input Operating Voltage Range up to 10.0V

• Low-Dropout Voltage (LDO):

- 120 mV (typical) @ 100 mA

- 380 mV (typical) @ 200 mA

• High Output Current: 250 mA (V_OUT= 5.0V)

• High-Accuracy Output Voltage: ±2% (max)

• Low Temperature Drift: ±100 ppm/°C (typical)

• Excellent Line Regulation: 0.2%/V (typical)

The MCP1701A 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

packages when operated with minimum V_IN– V_OUT

differentials. The MCP1701A offers improved startup

and transient response.

• Package Options: 3-Pin SOT-23A, 3-Pin SOT-89,

and 3-Pin TO-92

• Short Circuit Protection

• Standard Output Voltage Options:

- 1.8V, 2.5V, 3.0V, 3.3V, 5.0V

The MCP1701A has a tight tolerance output voltage

regulation of ±0.5% (typ.) and very good line regulation

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 MCP1701A

LDO also incorporates short circuit protection to ensure

maximum reliability.

Applications
