Description

The MCP1703 is a family of CMOS low dropout (LDO)

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

from 2.7V to 16.0V, making it an ideal choice for two to

six primary cell battery-powered applications, 9V alka-

line and one or two cell Li-Ion-powered applications.

The MCP1703 is capable of delivering 250 mA with

only 625 mV (typical) of input to output voltage differen-

tial (V

MCP1703 is typically ±0.4% at +25°C and ±3%

maximum over the operating junction temperature

range of -40°C to +125°C. Line regulation is ±0.1%

typical at +25°C.

Output voltages available for the MCP1703 range from

1.2V to 5.5V. The LDO output is stable when using only

1 µF of 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 the SOT-223-3, SOT-23A,

and SOT-89-3.
