FEATURES
GENERAL DESCRIPTION
The AMS3107 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 0.8mA or less when supplying 50mA loads. This unique
characteristic and the extremely low input-output differential required for proper regulation (0.2V for output currents of
100mA) make the AMS3107 ideal to use for standby power systems.
Internal circuitry of AMS3107 is protected from input fault conditions caused by reverse battery installation or input voltages
that exceed maximum rated input voltage. During line transients, such as load dump (40V) 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 AMS3107 series also includes internal current limiting, thermal shutdown, and
is able to withstand temporary power-up with mirror-image insertion.
The AMS3107 is offered in 3 lead TO-92, 8 lead SOIC, SOT-89, SOT-223 and TO-252 packages.
