G966
Global Mixed-mode Technology
2A Low Dropout Regulator with Enable
Features
General Description
„
„
The G966 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 2 amps. It operates with a VIN as low as 1.4V and
VPP voltage 5V with output voltage programmable as
low as 0.8V. The G966 features ultra low dropout,
ideal for applications where VOUT is very close to VIN.
Additionally, the G966 has an enable pin to further
reduce power dissipation while shutdown. The G966
provides excellent regulation over variations in line,
load and temperature. The G966 provides a power OK
signal to indicate if the voltage level of VO reaches
92% of its rating value.
