Description
The KA7632/KA7633 is a multi-output positive voltage
regulator designed to provide fixed precision output voltages
of 3.3V, 8V (KA7632) / 9V (KA7633) 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.
