CS5205A-1

CS5205A−1 5.0 A Adjustable Linear Regulator The CS5205A−1 linear regulator provides 5.0 A at an adjustable voltage with an accuracy of ±1%. Two external resistors are used to set the output voltage within a 1.25 V to 13 V 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. The circuit is designed to operate with dropout voltages as low as 1.0 V depending on the output current level. The maximum quiescent current is only 10 mA at full load. The regulator is fully protected against overload conditions with protection circuitry for Safe Operating Area (SOA), overcurrent and thermal shutdown. The CS5205A−1 is pin compatible with the LT1084 family of linear regulators but has lower dropout voltage. The regulator is available in TO−220−3 and surface mount D2PAK−3 packages.
