The S5JLM2931 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 current of 10mA) make the S5JLM2931 the ideal regulator

for standbe power system. Applications include memory standby circuits,

COMS 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 S5JLM2931 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 max. operating voltage, the regulator

will automatically shut down to protect both internal circuits and the load. The

S5JLM2931 cannot be harmed by temporary mirror-image insertion. Familiar

regulator features such as short circuit and thermal overload protection are

also provided.
