MCP1703

250 mA, 16V, Low Quiescent Current

Features

Description

• 2.0 µA Typical Quiescent Current

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.

• Input Operating Voltage Range: 2.7V to16.0V

• 250 mA Output Current for Output Voltages ≥ 2.5V

• 200 mA Output Current for Output Voltages < 2.5V

• Low Drop Out Voltage, 625 mV typical @ 250 mA

for V_R= 2.8V

• 0.4% Typical Output Voltage Tolerance

The MCP1703 is capable of delivering 250 mA with

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

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

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.

• Standard Output Voltage Options (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 capacitance

• Short-Circuit Protection

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.

• Overtemperature Protection

Applications

• Battery-powered Devices

• Battery-powered Alarm Circuits

• Smoke Detectors

Package options include the SOT-223-3, SOT-23A,

and SOT-89-3.

• CO²Detectors
