The CS5201−3 linear regulator provides 1.0 A @ 3.3 V reference at 1.0 A 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 operate with dropout voltages less than 1.2 V at 1.0 A output current.

The maximum quiescent current is only 10 mA at full load. Device protection includes overcurrent and thermal shutdown.

The CS5201−3 is pin compatible with the LT1086 family of linear regulators.

The regulator is available in TO−220−3, surface mount D2, and SOT−223 packages.
