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 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.
