CS5203-1

3.0 A Adjustable Linear Regulator

ON Semiconductor 

CS5203−1

3.0 A Adjustable Linear

Regulator

The CS5203−1 linear regulator provides 3.0 A at adjustable output

voltages with an accuracy of ±1.5 %. The device uses two external

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

The 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 1.4 V

at 3.0 A output current. Device protection includes overcurrent and

thermal shutdown.

The CS5203−1 is pin compatible with the LT1085 family of linear

regulators but has lower dropout voltage.

The regulator is available in TO−220−3 and surface mount D2PAK−3

packages.
