Description

The CS5203-1 linear regulator provides 3A at adjustable output voltages with an accuracy of ±1.5%. The device uses two external resistors to set the output voltage within a 1.25V to 5.5V range.

The regulator CS5203-1 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 CS5203-1 is designed to operate with dropout voltage less than 1.4V at 3A 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 CS5203-1 is available in TO-220 and surface mount D2 packages.
