CS5201−1/D

CS5201−1

1.0 A Adjustable Linear

Regulator

The CS5201−1 linear regulator provides 1.0 A with an output

voltage accuracy of ±1.0 %. The device uses two external resistors to

set the output voltage within a 1.25 V to 5.5 V range.

This regulator is intended for use as a post regulator and

microprocessor supply. The fast loop response and low dropout

voltage make this regulator ideal for applications where low voltage

operation and good transient response are important.

The circuit is designed to operate with dropout voltages less than 1.2 V

at 1.0 A output current. Device protection includes overcurrent and

thermal shutdown.

The CS5201 is pin compatible with the LT1086 family of linear

regulators.
