Features
Description
Output Currents up to 0.5A (output1 & 2)
GM7632 is a multi-output positive voltage regulator designed to provide fixed precision output voltages of 3.3V,
8V at current up to 0.5A and 5.1V at current up to 1A with
external PNP transistor.
Output Current up to 1A with External Transistor
(output3)
Fixed Precision Output 1 voltage 3.3V ± 2%
An internal reset circuit generates a reset pulse when the
output 1 decrease below the regulated value. Output2 & 3
can be disabled by TTL input. Protection features include
over voltage protection, short circuit protection and thermal
shutdown.
Fixed Precision Output 2 voltage 8V ± 2%
(GM7632)
Control Signal Generator for Output 3 voltage
(5.1V ± 2%)
Reset Facility for Output Voltage1
Output 2,3 with Disable by TTL Input
Current Limit Protection at Each Output

Notes:
1. To check the reset circuit ,the reset output is low to discharge the delay capacitor(=Cd). if it’s less than VO1-0.25V.
And the reset output is high when the delay capacitor voltage linearly increased by the interal current source(10µA)
if it’s more than VO1- 0.2V. The equations of delay time is same as below. Trd = (Cd X 2.5) / 10µA

2. Although guaranteed, these parameters are not 100% tested in production.
