DESCRIPTION
TheL4936N/NHare monolithic integrateddual voltage regulators with two very low dropout outputs and additionalfunctionssuchas power-onresetand input voltage sense. They are designed for supplying microcomputer controlled systems specially in automotive applications.

■ STANDBY OUTPUT VOLTAGE PRECISION 5V ± 2%
■ OUTPUT2 TRACKED TO THE STANDBY OUTPUT
■ OUTPUT 2 DISABLE FUNCTION FOR STANDBY MODE
■ VERY LOW QUIESCENT CURRENT, LESS THAN 250µA, IN STANDBY MODE
■ OUTPUT 2 VOLTAGE SETTABLE FROM 5 TO 20V
■ OUTPUT CURRENTS : I01 = 50mA,I02 = 500mA
■ VERY LOW DROPOUT (max 0.4V/0.6V)
■ OPERATING TRANSIENT SUPPLY VOLTAGE UP TO 40V
■ POWER-ON RESET CIRCUIT SENSING THE STANDBY OUTPUT VOLTAGE
■ POWER-ON RESET DELAY PULSE DEFINED BY THE EXTERNAL CAPACITOR
■ EARLY WARNING OUTPUT FOR SUPPLY UNDER VOLTAGE
■ THERMAL SHUTDOWN AND SHORT CIRCUIT PROTECTIONS
