7A, 1.5V Fixed Linear Regulator
1
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.
