G5JLM 2931
100mA Low Dropout Adjustable Voltage Regulator
Description
The G5JLM2931 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
G5JLM2931 the ideal regulator for standby 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 G5JLM2931 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
G5JLM2931 cannot be harmed by temporary mirror-image insertion. Familiar regulator features such as short circuit and thermal overload
protection are also provided.
