The G978 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 6 amps. It operates with VPP voltage 5V and
input voltage as low as 1.0V. The G978 features ultra
low dropout, ideal for applications where VO is very
close to VIN. Additionally, the G978 has an enable pin
to further reduce power dissipation while shutdown.
The G978 provides excellent regulation over variations
in line, load and temperature. The G978 provides a
power OK signal to indicate if the voltage level of VO
reaches 92% of its rating value.
The G978 is available in the power SOP-8 (FD) pack-
age. It is adjustable using external resistors.
