General Description

The MCP1700 is a family of CMOS low dropout (LDO)

voltage regulators that can deliver up to 250 mA of

current while consuming only 1.6 µA of quiescent

current (typical). The input operating range is specified

from 2.3V to 6.0V, making it an ideal choice for two and

three primary cell battery-powered applications, as well

as single cell Li-Ion-powered applications.

The MCP1700 is capable of delivering 250 mA with

only 178 mV of input to output voltage differential

(VOUT = 2.8V). The output voltage tolerance of the

MCP1700 is typically ±0.4% at +25°C and ±3%

maximum over the operating junction temperature

range of -40°C to +125°C.

Output voltages available for the MCP1700 range from

1.2V to 5.0V. The LDO output is stable when using only

1 µF 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-23, SOT-89 and

TO-92.
