Description:

The MCP1801 is a family of CMOS low dropout (LDO)

voltage regulators that can deliver up to 150 mA of

current while consuming only 25 µA of quiescent

current (typical). The input operating range is specified

from 2.0V to 10.0V, 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.

The MCP1801 is capable of delivering 100 mA with

only 200 mV (typical) of input to output voltage

differential (V

OUT

= 3.3V). The output voltage tolerance

of the MCP1801 at +25°C is typically ±0.4% with a

maximum of ±2%. Line regulation is ±0.01% typical at

+25°C.

The LDO output is stable with a minimum of 1 µF of

output capacitance. Ceramic, tantalum, or aluminum

electrolytic capacitors can all be used for input and

output. Overcurrent limit with current foldback provides

short-circuit protection. A shutdown (SHDN) function

allows the output to be enabled or disabled. When

disabled, the MCP1801 draws only 0.01 µA of current

(typical).

The MCP1801 is available in a SOT-23-5 package.

Applications:

•

Battery-powered Devices

Battery-powered Alarm Circuits

Smoke Detectors

Detectors

Pagers and Cellular Phones

Wireless Communications Equipment

Smart Battery Packs

Low Quiescent Current Voltage Reference

PDAs

Digital Cameras

Microcontroller Power

Solar-Powered Instruments

Consumer Products

Battery Powered Data Loggers
