GENERAL DESCRIPTION
The AMS3102 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 0.3mA or less when supplying 10mA loads. This unique
characteristic and the extremely low input-output differential required for proper regulation (0.25V for output currents of
100mA) make the AMS3102 ideal to use for standby power systems.
Internal circuitry of AMS3102 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 AMS3102 series also includes internal current limiting, thermal shutdown, and
is able to withstand temporary power-up with mirror-image insertion.
The AMS3102 is offered in the 3-pin TO-92 package, SOT-89, 3 lead SOT-23, 5 lead SOT-23 and 8 lead SOIC packages. The
device is provided with On/Off pin in SOT-23 5L and in 8 lead SOIC package.
