G9233

Global Mixed-mode Technology Inc. G9233 3.3V 2A Low Dropout Regulator with Disable Features Dropout voltage 0.5V @ IO = 2A Output current in excess of 2A Output voltage accuracy ±2.5% Quiescent current, typically 5mA Internal short circuit current limit Internal over temperature protection TO220 4pin Full-Mold package ON/OFF control General Description The G9233 positive 3.3V voltage regulator features the ability to source 2A of output current. The dropout voltage is 0.5V at 2A output current. The typical quiescent current is 5mA. Furthermore, the quiescent current is smaller when the regulator is in the dropout mode (VIN < 3.3V). 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 Vdis pin is provided to disable the output when needed. Ordering Information ORDER NUMBER G9233TF1T G9233TH1T G9233TH1Tf MARKING G9233 G9233 G9233 TEMP.

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 150°C and IC will go into thermal shutdown. For the TO 220 package, θJA is 60°C/W (No heat sink). 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 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 2% below its nominal value, dropout voltage is affected by junction temperature, load current and minimum input supply requirements. 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. 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. Maximum Power Dissipation The maximum total device dissipation for which the regulator will operate within specifications. Quiescent Bias Current Current which is used to operate the regulator chip and is not delivered to the load.
