Global Mixed-mode Technology Inc. G9965 1.5A Low Dropout Regulator with Enable Features 1.5V, 1.8V, 2.5V and Adjustable Outputs Over Current and Over Temperature Protection 500mV Dropout @1.5A Enable Pin 16A Quiescent Current in Shutdown TO-263-5 Package 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 provides over current and over temperature protection functions. The G9965 is available with 1.5V, 1.8V, 2.5V and adjustable outputs in TO-263-5 package.
