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.
