AMS500 series consists of positive fixed and adjustable voltage regulators ideally suited for use in battery-powered systems. These devices feature 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 available in the 3-pin TO-92 package, SOT-89 and 5 lead SOT-23 packages and operates over the industrial temperature range.
