CS5207-3

The CS5207-3 linear regulator pro-

vides 7A at 3.3V with an accuracy

of ±2%.

The regulator is intended for use as

post regulator and microprocessor

supply. The fast loop response and

low dropout voltage make this reg-

ulator 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 cur-

rent is only 10mA at full load.

The regulator is fully protected

against overload conditions with

protection circuitry for Safe

Operating Area (SOA), overcurrent

and thermal shutdown.

The CS5207-3 is available in 3 lead
