Linear Regulators

The CS5204−x series of linear regulators provides 4.0 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 regulators are available in TO−220−3 and surface mount
