General Description The G955 positive 2.85V voltage regulator features the ability to source 1A of output current with a dropout voltage of typically 0.5V over the entire operating temperature range. A low quiescent current is provided over the entire current output current range. The typical quiescent current is 0.4mA. Furthermore, the quiescent current is smaller when the regulator is in the dropout mode ( VIN < 2.85V). Familiar regulator features such as over temperature, over current, and over voltage Features Dropout voltage typically 0.5V @ IO = 1A Output current in excess of 1A Output voltage accuracy +2% Quiescent current, typically 400µA Internal short circuit current limit Internal over temperature protection Internal over voltage protection Typical Application IO VIN VOUT G955 C1 .47μF IQ COUT 10μF Absolute Maximum Ratings (Note 1) Input Voltage 10V Internal Power Dissipation(Note 2) Internally Limited Maximum Junction Temperature 150℃ Storage Temperature Range -65℃≤ TJ ≤+150℃ Lead Temperature, Time for Wave Soldering TO-220 (T) Package 260℃,10s TO-252 (T) Package TO-263 (S) Package ESD Susceptibility (Note 3) 260℃, 4s 260℃, 4s 2kV Operating Conditions (Note 1) Input Voltage -0.3V~10V Temperature Range 0℃≤ TA ≤125℃ Pin Configuration Package TO-220 Pin No. TO-252 TO-263 1 VIN GND VIN GND VIN GND 2 GND VOUT GND VOUT GND VOUT 3 VOUT VIN VOUT VIN VOUT VIN Global Media Technology Inc.

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. Note 2: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ, the junction-to-ambient thermal resistance, θJ A, and the ambient temperature, TA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The value of θJ A (for device in still no heatsink) is 60℃/W for the TO-220 package. 80℃/W for the TO-263 package, 174℃/W for the SOT-223 and SOT-89 package. The effective value of θJ A can be reduced by using a heatsink (see Application Hints for specific information on heatsinking). The values of θJ A and θJ C for the K02A package are 39℃/W and 4℃/W respectively. Note 3: ESD rating is based on the human body model, 100pF discharged through 1.5kΩ.
