General Description

The G961 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 1 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 G961 provides excellent regulation over variations in line, load and temperature.

The SOT-89-5 is available with 1.5V, 1.8V and 2.5V internally preset outputs that are also adjustable using external resistors.
