CS5201-1 Datasheet, PDF (1/9 Pages) Cherry Semiconductor Corporation – 1A Adjustable Linear Regulator

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.
The regulator is available in TO−220, surface mount D², and
SOT−223 packages.
