REGULATOR
DESCRIPTION
The
@vic AV2950/2951 is a monolithic integrated voltage
regulator with low dropout voltage, and low quiescent current.
It includes many features that suitable for different
applications. Available in 3-pin TO-92, DIP-8 and SOP-8
packages.
FEATURES
*High accuracy 2.5, 3.0, 3.3, 3.6 or 5V fixed output for
TO-92, SOP-8 package.
*Extremely low quiescent current and dropout voltage.
*Extremely tight load and line regulation.
*Current and thermal limiting.
*Very low temperature coefficient.
*Logic controlled shutdown and error flag available for DIP
and SOP package.
*Output voltage programmable for DIP and SOP package.
APPLICATIONS
*Battery powered equipment.
*High efficient linear regulator down to 1.24V.
*Cellular phones.
