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 0.5Aand 12V

at current up to 1A with external PNP transistor.

An internal reset circuit generates a reset pulse when the

output 1 decreases below the regulated value. Output2 & 3

can be disabled by TTL input. Protection features include

over voltage protection, short circuit protection and thermal

shutdown.
