PRODUCT DESCRIPTION

The SPX2931 is a low power voltage regulator. This device is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable computers. The SPX2931 features offers very low quiescent currents (0.4 mA.), and very low drop output voltage (typ. 50 mV at light load and 300 mV at 100 mA). Other features include the logic compatible On/Off input which enables the regulator to be switched on and off. The SPX2931 is offered in a 3-pin TO-92/TO-220 package and SOT-89/SO-8 package.
