CS5203-3 Datasheet | Cherry Semiconductor Corporation

Description The CS5203-3 linear regulator provides a 3.3V reference at 3A with an output voltage accuracy of ±1.5%. 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 provide 3A of output current with dropout voltages of less than 1.15V. The maximum quiescent current is only 10m A at full load. Device protection includes overcurrent and thermal shutdown. The CS5203-3 is pin patible with the LT1085 family of linear regulators. The regulator is available in a surface mount D2 package.
