2A ULTRA LOW DROPOUT

LINEAR REGULATOR



DESCRIPTION

The UTC LR18220 series of high performance ultra-low dropout

linear regulators operates from 2.5V to 6V input supply and

provides ultra-low dropout voltage, high output current with low

ground current. These ultra-low dropout linear regulators respond

fast to step changes in load which makes them suitable for low

voltage micro-processor applications. The UTC LR18220 is

CMOS-based positive voltage and a very low dropout regulator IC

which allows low quiescent current operation independent of output

load current. This CMOS process also allows the UTC LR18220 to

operate under extremely low dropout conditions.



FEATURES

* Compatible with low ESR MLCC as Input/Output Capacitor

* Good Line and Load Regulation

* Guaranteed Output Current of 2A

* Available in SOP-8 Package
