7A, 1.5V Fixed Linear Regulator

CS5207-2

The CS5207-2 provides 7A at 1.5V

with an accuracy of ± 2%.

The regulator is intended for use as

an active termination for the GTL

bus on Intel based motherboards.

The fast loop response and low

dropout voltage make these regula-

tors 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 regulators are fully protected

against overload conditions with

protection circuitry for Safe

Operating Area (SOA), overcurrent

and thermal shutdown.

The CS5207-2 is available in TO-220

packages.
