LM2935
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.
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), and load dump transients (+60 V).
