APPLICATION
PRODUCT DESCRIPTION
The AS2931 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 AS2931 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 AS2931 is offered in a 3-pin TO-92/TO-220
package compatible with other 5V regulators and SOT-89/SO-8 package.
The regulator output voltage may be internally pin-strapped for a 3.5V, 3.3V, 3.0V, or programmed from 3V to 24V with an external
pair of resistors.
