The SPX2930 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 SPX2930 features offers very low quiescent currents (0.4 mA), and very

low drop output voltage (50 mV at light load and 300 mV at 150 mA). The SPX2930 is offered

in a 3-pin TO-92, TO-220 and SOT-89 package.

APPLICATIONS

■ Portable Instrumentation

■ Cordless Telephones

■ Radio Control Systemss

■ Portable Consumer Devices

■ Toys

■ Radio Controlled Systems
