General Description
The G972 is a high performance positive voltage
regulator designed for use in applications requiring
very low Input voltage and very low dropout voltage at
up to 5 amps. It operates with VPP voltage 5V and
output voltage programmable as low as 0.8V. The
G972 features ultra low dropout, ideal for applications
where VOUT is very close to VIN. Additionally, the G972
has an enable pin to further reduce power dissipation
while shutdown. The G972 provides excellent regula-
tion over variations in line, load and temperature. The
G972 provides a power OK signal to indicate if the
voltage level of VO reaches 92% of its rating value.
The G972 is available in the power SOP-8 (FD) pack-
age. It is adjustable using external resistors.
