ON/OFF, Keep-Alive and Safety

Latch-Off Control Diagrams

Note: If Keep-Alive is provided by a microprocessor powered by the output

voltage of the LM9074, the logic “1” voltage level will track VOUT as the

regulator turns OFF.

Simple ON/OFF control

(Keep-Alive input must be high to turn OFF output)

10130518

Keep-Alive Mode; Turn ON with ON/OFF control,

Keep output biased with Keep-Alive input,

Turn OFF with Keep-Alive (Keep-Alive low keeps

output ON, Keep-Alive going high turns output OFF)
