GENERAL DESCRIPTION
The AMS2931 series consists of positive fixed and adjustable voltage regulators ideally suited for use in battery-powered
systems. These devices feature 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 currents of
10mA) make the AMS2931 ideal to use for standby power systems.
Originally designed for automotive applications, the AMS2931 and all regulated circuitry are protected from input fault
conditions caused by reverse battery installation or two battery jump starts. During line transients, such as 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 AMS2931 series also includes internal current
limiting, thermal shutdown, and is able to withstand temporary power-up with mirror-image insertion.
The AMS2931 is offered in the 3-pin TO-92 package, 8-pin plastic SOIC, TO-220 and TO-263 packages.
