MCP1702

250 mA Low Quiescent Current LDO Regulator

Features

Description

• 2.0 µA Quiescent Current (typical)

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 and one or two cell Li-Ion-powered

applications.

• Input Operating Voltage Range: 2.7V to 13.2V

• 250 mA Output Current for Output Voltages ≥ 2.5V

• 200 mA Output Current for Output Voltages < 2.5V

• Low Dropout (LDO) voltage

- 625 mV typical @ 250 mA (V_OUT= 2.8V)

• 0.4% Typical Output Voltage Tolerance

• Standard Output Voltage Options:

The MCP1702 is capable of delivering 250 mA with

only 625 mV (typical) of input to output voltage

differential (V_OUT= 2.8V). The output voltage tolerance

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.

- 1.2V, 1.5V, 1.8V, 2.5V, 2.8V,

3.0V, 3.3V, 4.0V, 5.0V

• Output voltage range 1.2V to 5.5V in 0.1V

Increments (50 mV increments available upon

request)

• Stable with 1.0 µF to 22 µF Output Capacitor

• Short-Circuit Protection

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
