loads. This unique characteristic and the extremely low in-put-
output differential required for proper regulation (0.2V for
output currents of 10mA) make the LM2931 the ideal regulator
for standby power systems. Applications include memory
standby circuits, CMOS and other low power processor power
supplies as well as systems demanding as much as 100mA of
output current.
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 can
not be harmed by temporary mirror-image insertion. Familiar
regulator features such as short circuit and thermal overload
protection are also provided.
