G930/G931 Global Mixed-mode Technology Inc. 3.5V 400mA Low Dropout Regulator Features General Description Dropout voltage typically 0.8V @ IO = 400mA Output current in excess of 400mA Output voltage accuracy +3%/-2% Quiescent current, typically 600µ µA Internal short circuit current limit Internal over temperature protection 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.

Operating Conditions are conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics. Note2: The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance, θJA, and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is Tjmax-TA / θJA. If this dissipation is exceeded, the die temperature will rise above 130°C and IC will go into thermal shutdown. For the G930/G931 in SOT 89 package, θJA is 250°C/W. (See Recommended Minimum Footprint). The safe operation in SOT 89, it can see “Typical Performance Characteristics” (Safe Operating Area). Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible. Note4: The type of output capacitor should be tantalum or aluminum. Definitions Load Regulation The change in output voltage for a change in load current at constant chip temperature. The measurement is made under conditions of low dissipation or by using pulse techniques such that average chip temperature is not significantly affected. Dropout Voltage The input/output Voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 100mV below its nominal value, dropout voltage is affected by junction temperature, load current and minimum input supply requirements. Maximum Power Dissipation The maximum total device dissipation for which the regulator will operate within specifications. Line Regulation The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that average chip temperature is not significantly affected. Quiescent Bias Current Current which is used to operate the regulator chip and is not delivered to the load.
