CS5208-1

CS5208−1 8.0 A LDO 3−Pin Adjustable Linear Regulator The CS5208−1 linear regulator provides 8.0 A at adjustable voltages from 1.25 V to 4.5 V. This adjustable device requires two external resistors to set the output voltage and provide the minimum load current for proper regulation. 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 as low as 1.0 V at 8.0 A. The regulator is protected against overload conditions with overcurrent and thermal shutdown protection circuitry. The regulator is available in a TO−220 package.
