General Description
The G953 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 1.5 Amps. G953 fea-
tures 500mV dropout voltages and very low ground
current. Although designed for high current loads,
these devices are also useful in lower current, ex-
tremely low dropout-critical systems, where their
minimal dropout voltage and ground current values are
important characteristics.
The G953 provides excellent regulation over variations
in line, load and temperature.
Applications
Battery powered systems
Motherboards
Peripheral cards
Network cards
