MCP1703

250 mA, 16V, Low Quiescent Current LDO Regulator

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

alkaline 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 Dropout Voltage, 625 mV typical @ 250 mA

for V_R= 2.8V

• 0.4% Typical Output Voltage Tolerance

• Standard Output Voltage Options:

The MCP1703 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 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.

- 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 Ceramic Output

Capacitance

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,

2x3 DFN-8, and SOT-89-3.

• Short-Circuit Protection

• Overtemperature Protection

Applications:

• Battery-Powered Devices

• Battery-Powered Alarm Circuits

• Smoke Detectors

Package Types

• CO²Detectors

• Pagers and Cellular Phones

• Smart Battery Packs
