General Description
The G962 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 to regular
LDOs, it can be used to supply 2.5V on motherboards
or 1.5V, 1.8V on peripheral cards from the 3.3V supply
thus allowing the elimination of costly heatsinks. An
enable pin further reduces power dissipation while
shut down. The G962 provides excellent regulation
over variations in line, load and temperature.
The TO-252-5 is available with 1.5V, 1.8V and 2.5V
internally preset outputs that are also adjustable using
external resistors.
