G9125 Global Mixed-mode Technology Inc. 2.5V 1A Low Dropout Regulator with Enable Features General Description The G9125 positive 2.5V voltage regulator features the ability to source 1A of output current. The dropout voltage is 0.6V at 1A output current. The typical quiescent current is 5mA. Furthermore, the quiescent current is smaller when the regulator is in the dropout mode. Dropout voltage 0.6V @ IO = 1A Output current in excess of 1A Output voltage accuracy ±2.5% Quiescent current, typically 5mA Internal short circuit current limit Internal over temperature protection TO-220 4pin Full-Mold, TO-252-5 package ON/OFF control Familiar regulator features such as over temperature and over current protection circuits are provided to prevent it from being damaged by abnormal operating conditions. A VEN pin is provided to disable the output when needed. Ordering Information ORDER NUMBER PIN OPTION 2 3 MARKING TEMP.
