Order this document by LM2935/D LM2935 Low Dropout Dual Voltage Regulator The LM2935 is a dual positive 5.0 V low dropout voltage regulator, LOW DROPOUT designed for standby power systems. The main output is capable of supplying 750 mA for microprocessor power, and can be turned “on” and DUAL VOLTAGE REGULATOR “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. SEMICONDUCTOR The total device features a low quiescent current of 3.0 mA or less when TECHNICAL DATA supplying 10 mA from the standby output. This part was designed for harsh automotive environments and is therefore immune to many input supply voltage problems such as reverse battery (–12 V), double battery (+24 V),
