General Description
The G954 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 2 Amps. Since it has
superior dropout characteristics compared with regular
LDOs, it can be used to supply 2.5V on motherboards
or 1.5V, 1.8V on peripheral cards from the power sup-
ply thus allowing the elimination of costly heatsinks.
The G954 provides excellent regulation over variations
in line, load and temperature. It provides over current
and over temperature protection functions.
The G954 is available with 1.2V, 1.5V, 1.8V, 2.5V and
adjustable outputs in TO-263 & TO-263T package.
