General Description
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 V_IN 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 V_OUT is very close
to V_IN. 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.
The G969A is available in the power MSOP-8 package.
It is available with 1.2V, 1.5V, 1.8V and 2.5V internally
preset outputs that are also adjustable using external
resistors.
