DESCRIPTION
It is a monolithic Multifunction Voltage Regulator; it contains 3 regulators, (REG1, REG2, REG3) each one with an enable input and a feedback input, to allow the voltage setting via external resistive divider.
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).
■ 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
