L4909
L4909 is EXTERNALLY ADJUSTABLE MULTIFUNCTION REGULATOR manufactured by STMicroelectronics.
EXTERNALLY ADJUSTABLE MULTIFUNCTION REGULATOR s
3 OUTPUTS
- Vo1 : output voltage variable from 5 to 12 V; limit current : 1.2 A.
- Vo2 : output voltage variable from 5 to 12 V; limit current : 1.2 A.
- Vo3 : output voltage variable from 5 to 12 V; limit current : 1.2 A. ENABLE INPUT FOR EACH REGULATOR FEEDBACK INPUT FOR EACH REGULATOR SHORT CIRCUIT PROTECTION TO GROUND OVERCURRENT WARNING DRIVER FOR EXTERNAL SCR (CROWBAR PROTECTION) THERMAL SHUTDOWN
Each regulator is current limited and furthermore an OR-ed warning signal is output (open collector, active low output) when the current in a regulator goes above an over-current threshold (1 A typ for any regulator). When one output...
