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 LM9070, the logic “1” voltage level will track V
OUT
as the regulator turns
OFF.
Output Capacitor ESR
DS012831-15
Maximum Power Dissipation
(TO-220 Package)
DS012831-16
Maximum Power Dissipation
(TO-263 and SO-20 Packages)
DS012831-17
Simple ON/OFF control
(Keep-Alive input must be high to turn OFF output)
DS012831-18
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)
DS012831-19
Switch ON with ON/OFF input; Keep output
biased with Keep-Alive; Hold ouput ON with
ON/OFF; Turn OFF with ON/OFF input.
(Temporary Keep-Alive Mode)
DS012831-20
Safety Latch OFF of V
when in Keep-Alive Mode
(ON/OFF going high required to turn Output back ON)
DS012831-21
