MCP1703A

250 mA, 16V, Low Quiescent Current LDO Regulator

Features:

Description:

• Reduced Ground Current During Dropout

• Faster Startup Time

The MCP1703A is an improved version of the

MCP1703 low dropout (LDO) voltage regulator 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.

• 2.0 µA Typical Quiescent Current

• 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

The MCP1703A 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 MCP1703A 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.

• 0.4% Typical Output Voltage Tolerance

• 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)

Output voltages available for the MCP1703A 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.

• Stable with 1.0 µF to 22 µF Ceramic Output

Capacitance

• Short-Circuit Protection

• Overtemperature Protection

• Battery-Powered Devices

• Battery-Powered Alarm Circuits

• Smoke Detectors
