General Description
The G9965 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 1.5 Amps. Since it
has superior dropout characteristics compared with
regular LDOs, it can be used to supply 2.5V from the
3.3V supply, or to supply 1.8V and 1.5V from the 2.5V
supply. Thus allowing the elimination of costly heatsinks.
An enable pin further reduces power dissipation while
shut down. The G9965 provides excellent regulation
over variations in line, load and temperature. It pro-
vides over current and over temperature protection
functions.
The G9965 is available with 1.5V, 1.8V, 2.5V and ad-
justable outputs in TO-263-5 package.
