Description

The MCP1702 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 13.2V, making it an ideal choice for two to

six primary cell battery-powered applications, 9V

alkaline

applications.

The MCP1702 is capable of delivering 250 mA with

only 625 mV (typical) of input to output voltage

differential (V

of the MCP1702 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 MCP1702 range from

1.2V to 5.0V. 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

overtemperature shutdown provide a robust solution

for any application.

Package options include the SOT-23A, SOT-89-3, and

TO-92.
