FIXED MULTI - OUTPUT REGULATOR
Description
GM7632 is a multi-output positive voltage regulator de-
signed 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.
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.
