GENERAL DESCRIPTION
The AMS500 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
low input-output differential required for proper regulation (0.2V for output currents of 100mA) make the AMS500 ideal to use
for standby power systems.
Internal circuitry of AMS500 is protected from input fault conditions caused by input voltages that exceed maximum rated input
voltage. During line transients, 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 AMS500 series also includes
internal current limiting, thermal shutdown.
The AMS500 is offered in 3 lead TO-92, SOT-89, SOT-223 and 5 leads SOT-23 packages.
