GM2931

The GM2931 positive low dropout voltage regulators are available in adjustable and fixed-output versions. The GM2931s have quiescent current of 1mA or less when supplying 10mA loads. Together with the extremely low dropout voltage required for proper regulation (0.2V for output currents of 10mA) these qualities make the GM2931 the ideal regulator for standby power systems. Applications include memory standby circuits, CMOS and other low power processor power supplies and any precision systems requiring up to 100mA of output current.

The GM2931 protects itself and the regulated circuitry from reverse battery installations or two-battery jumps up to 20V. During line transients, such as a load dump (60V) when the input voltage to the regulator might temporarily exceed the specified maximum operating voltage, the GM2931 automatically shuts down to protect both itself and the load. The GM2931 is not damaged by temporary mirror-image insertion. Of course, the GM2931 includes common regulator features such as short circuit and thermal overload protection.
