L4903 is a dual 5V regulator with reset and disable functions. It provides output currents of 50mA and 100mA. The fixed precision output voltage is 5V±2%. The reset function is controlled by the input voltage and output 1 voltage. The timing of the reset function can be externally programmed. The reset output level is related to output 2. Output 2 is internally switched with active discharging. Output 2 can be disabled using a logical input. It has low leakage current, less than 1µA at output 1. It also features input overvoltage protection up to 60V. The reset output is normally low. The output transistors have SOA protection. It provides short circuit and thermal overload protection.
