CS5203A-1

CS5203A−1, CS5203A−2, CS5203A−3, CS5203A−5 3.0 A Adjustable, and Fixed 1.5 V, 3.3 V and 5.0 V Linear Regulators The CS5203A series of linear regulators provides 3.0 A at adjustable and fixed voltages with an accuracy of ±1.0% and ±2.0% respectively. The adjustable version uses two external resistors to set the output voltage within a 1.25 V to 13 V range. The regulators are intended for use as post regulators and microprocessor supplies. The fast loop response and low dropout voltage make these regulators 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 regulators are fully protected against overload conditions with protection circuitry for Safe Operating Area (SOA), overcurrent and thermal shutdown. The CS5203A is pin compatible with the LT1085 family of linear regulators but has lower dropout voltage. The regulators are available in TO−220−3 and surface mount D2PAK−3 packages.
