DESCRIPTION
The L4903 is a monolithic low drop dual 5 V regulatordesigned mainly for supplying microprocessor systems.
Reset, data save functions and remote switch on/off controlcan be realized.
■ OUTPUT CURRENTS : I01 = 50mA I02 = 100mA
■ FIXED PRECISION OUTPUT VOLTAGE 5V ± 2
■ RESET FUNCTION CONTROLLED BY INPUT VOLTAGE AND OUTPUT 1 VOLTAGE
■ RESET FUNCTION EXTERNALLY PROGRAMMABLE TIMING
■ RESET OUTPUT LEVEL RELATED TO OUTPUT 2
■ OUTPUT 2 INTERNALLY SWITCHED WITH ACTIVE DISCHARGING
■ OUTPUT 2 DISABLE LOGICAL INPUT
■ LOW LEAKAGE CURRENT, LESS THAN 1μA AT OUTPUT 1
■ INPUT OVERVOLTAGE PROTECTION UP TO 60V
■ RESET OUTPUT NORMALLY LOW
■ OUTPUT TRANSISTORS SOA PROTECTION
■ SHORT CIRCUIT AND THERMAL OVERLOAD PROTECTION
