PRODUCT DESCRIPTION

The CLM2931 is a positive 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 CLM2931 features very low quiescent current (0.4mA) and very low drop output voltage (typ. 50mV at light load and 300mV at 100mA). other features include the logic-compatible on/off input which enables the regulator to be switched on and off.

The regulator output voltage may be internally pin-strapped for a 5V, 3V, 3.3V, 3.5V, 4.0V, 4.5V or programmed from 3V to 24V with an external pair of resistors. Using Calogic’s design, process and testing technique make the CLM2931 superior over similar products.
