CS5207A−1

7.0 A LDO 3−Pin Adjustable

Linear Regulator

The CS5207A−1 linear regulator provides 7.0 A at adjustable

voltages from 1.25 V to 5.0 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 7.0 A.

This regulator is protected against overload conditions with

overcurrent and thermal shutdown protection circuitry.

The CS5207A−1 is pin compatible with the LT1584 family of linear

regulators but has lower dropout voltage and faster transient response.

This regulator is available in a TO−220 package.
