General Description
The KA7630/KA7631 is a multi-output positive voltage regulator
designed to provide fixed precision output voltages of
5.1V, 8V (7630) / 9V (7631) at current up to 0.5A and12V
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.
