DESCRIPTION

The FC7630 is a multi-output positive voltage regulator

designed to provide fixed precision output voltages of 5.1V, 8V

at current up to 0.5A and 12V 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.
