DESCRIPTION

The SPX2808 is a low power, positive 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 SPX2808 features offers very low quiescent currents (0.4mA), and very

low drop output voltage (50mV at light load and 450mV at 300mA). The SPX2808 is offered in

a 3-pin SOT-223 and SOT-89 package.
