General Description
The G9967 is a high performance positive voltage
regulator designed for use in applications requiring
very low dropout voltage at up to 3 Amps. Since it has
superior dropout characteristics compared with regular
LDOs, it can be used to supply adjustable voltage on
motherboards or on peripheral cards from the power
supply thus allowing the elimination of costly heatsinks.
An enable pin further reduces power dissipation while
shut down. The G9967 provides excellent regulation
over variations in line, load and temperature. It pro-
vides over current and over temperature protection
functions.
The G9967 is available with adjustable outputs in
TO-263-5 package.
