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.
