G953
1.5A Low Dropout Regulator
Features
General Description
Fixed output voltage
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.
Output current up to 1.5A
Over current and over temperature protection
Low dropout voltage 500mV@1.5A
Low ground current
SOT-223 package
Applications
Battery powered systems
Motherboards
Peripheral cards
Network cards
Set Top Boxes
Notebook Computers
The G953 provides excellent regulation over variations
in line, load and temperature.
