FC7630 SP FIXED- MULTI-OUTPUT REGULATORS
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.
FEATURES
