CS5205-1

CS5205-1,-3,-5 CS5205-1,-3,-5 5A Adjustable, and 3.3V and 5V Fixed Linear Regulators Description The CS5205-X series of linear regulators provides 5A at adjustable and fixed voltages with an accuracy of ±1% and ±2% respectively. The adjustable version uses two external resistors to set the output voltage within a 1.25V to 13V 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 1V depending on the output current level. The maximum quiescent current is only 10mA at full load. The regulators are fully protected against overload conditions with protection circuitry for Safe Operating Area (SOA), overcurrent and thermal shutdown. The CS5205-X is pin compatible with the LT1084 family of linear regulators but has lower dropout voltage. The regulators are available in TO220 and surface mount D2 packages.
