Low Dropout Regulator Features 2µA Quiescent Current

( 1 Jan 2008 )

Microchip Technology Inc.'s MCP1703 low dropout regulator (LDO) features a rated current of 250mA and is available in a three-pin SOT-223 package. The device is suitable for applications requiring long battery runtimes and high tolerance for input-voltage variations such as smoke detectors, fire alarms and thermostats.

With a low quiescent current of 2¦ÌA, the device requires a small amount of current to maintain regulation, thereby decreasing wasted energy. It supports input voltages of up to 16V so that it can be used in a variety of high-voltage DC and multi-cell alkaline or Li-ion battery applications. The LDO features over-voltage protection and thermal shutdown.
