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.
