General Description

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.

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

differentials. The MCP1701A offers improved startup

and transient response.

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.

Package options include the 3-pin SOT-23A, 3-pin

SOT-89 and 3-Pin TO-92.
