G926 Global Mixed-mode Technology Inc. Dual 500mA LDO Regulator General Description Features The G926A is a dual low dropout regulator with VOUT1 2.5V/500mA and VOUT2 3.3V/500mA, G926B is with VOUT1 1.8V/500mA and VOUT2 3.3V/500mA. The dropout voltage is typically 1V with 500mA load. A low quiescent current is typical 200µA. Wide Input Voltage Range: 4.3V~6.5V IO = 500mA, VO UT1=2.5V/1.8V, Dropout Voltage Typically 1V; VOUT2=3.3V, Dropout Voltage Typically 1V Output Current in Excess of 500mA Output Voltage Accuracy ±2% Quiescent Current, Typically 200µA Internal Short Circuit Current Limit Internal Over Temperature Protection Familiar regulator features such as over temperature and current limit protection circuits are provided to prevent it from being damaged by abnormal operating conditions. The G926 comes in a SOP-8 and SOP-8 (FD) with power-pad package.
