Linear Regulators
http://onsemi.com
The CS5205–x series of linear regulators provides 5.0 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.
