LM2931

Series Low Dropout Regulators

General Description

The LM2931 positive voltage regulator features a very low

quiescent current of 1mA or less when supplying 10mA loads.

This unique characteristic and the extremely low input-output

differential required for proper regulation (0.2V for output cur-

rents of 10mA) make the LM2931 the ideal regulator for

standby power systems. Applications include memory stand-

by circuits, CMOS and other low power processor power

supplies as well as systems demanding as much as 100mA

of output current.

Designed originally for automotive applications, the LM2931

and all regulated circuitry are protected from reverse battery

installations or 2 battery jumps. During line transients, such

as a load dump (60V) when the input voltage to the regulator

can momentarily exceed the specified maximum operating

voltage, the regulator will automatically shut down to protect

both internal circuits and the load. The LM2931 cannot be

harmed by temporary mirror-image insertion. Familiar regu-

lator features such as short circuit and thermal overload pro-

tection are also provided.

The LM2931 family includes a fixed 5V output (±3.8% toler-

ance for A grade) or an adjustable output with ON/OFF pin.
