Global Mixed-mode Technology
1.5A Low Dropout Regulator with Dual Input Voltage
Features
General Description
Adjustable Output Low to 0.8V
The G969A 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 1.5 amps. It operates with a VIN as low as 1.4V
and VPP voltage 5V with output voltage programma-
ble as low as 0.8V. The G969A features ultra low
dropout, ideal for applications where VOUT is very close
to VIN. The G969A provides excellent regulation over
variations in line, load and temperature. The G969A
provides a power OK signal to indicate if the voltage
level of VO reaches 92% of its rating value.
