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).

• Two Regulated 5.0 V Outputs

• Main Output Current in Excess of 750 mA

• On/Off Control of Main Output

• Standby Output Current in Excess of 10 mA

• Low Input/Output Differential of Less than 0.6 V at 500 mA

• Short Circuit Current Limiting

• Internal Thermal Shutdown

• Low Voltage Indicator Output

• Designed for Automotive Environment Including

• Reverse Battery Protection

• Double Battery Protection

• Load Dump Protection

• Reverse Transient Protection

• Economical 5–Lead TO–220 Package with Two Optional Leadforms

• Also Available in Surface Mount D

*The main output
is “Off” with switch
S1 open.

An input bypass capacitor is recommended if the regulator is located more than 4

″

from the supply
input filter. The LM2935 is not internally compensated and thus requires an external output capacitor
for stability. A minimum capacitance of 10

µ

F is recommended. The actual capacitance value is
dependent upon load current, temperature, and the capacitor’s equivalent series resistance (ESR).
The least stable condition is encountered at maximum load current and minimum ambient
temperature.
