G930/G931
3.5V 400mA Low Dropout Regulator
Features
Dropout voltage typically 0.8V @ IO = 400mA Output current in excess of 400mA Output voltage accuracy +3%/-2% Quiescent current, typically 600µA Internal short circuit current limit Internal over temperature protection
General Description
The G930/G931 positive 3.5V voltage regulator features the ability to source 400mA of output current with a dropout voltage of typically 0.8V over the entire operating temperature range. A low quiescent current is provided over the entire output current range. The typical quiescent current is 0.6mA. Furthermore, the quiescent current is smaller when the regulator is in the dropout mode (VIN < 3.5V). Familiar regulator features such as over temperature and over current protection circuits are provided to prevent it from being damaged by abnormal operating conditions.
