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 lo w drop output voltage
(typ. 50mV at lig ht load and 300mV at 100mA). ot her 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 product s.
