Low Dropout Dual Voltage Regulator

The LM2935 is a dual positive 5.0 V low dropout voltage regulator, designed for standby power systems. The main output is capable of supplying 750 mA for microprocessor power, and can be turned “on” and “off” by the switch/reset input. The other output is dedicated for standby operation of volatile memory, and is capable of supplying up to 10 mA loads. The total device features a low quiescent current of 3.0 mA or less when supplying 10 mA from the standby output.
