G9611

www.DataSheet4U.com Global Mixed-mode Technology Inc. G9611 Low-Dropout, 300mA Linear Regulator with Reset Features „ „ „ „ „ „ „ „ „ General Description The G9611 are low-dropout, linear regulator with reset function supply 3.4V, 3.3V or 2.5V output for currents up to 300mA. They are available in a 700mW SOP 8 package. Typical dropouts are 320mV at 300mA. Shutdown turns off linear regulator function. Other features include foldback current limiting and thermal overload protection. The reset function in G9611 detect VCC level with hysteresis, keeping it asserted for time delay determined by external capacitor. The reset output is active low open-drain output. The detection threshold are 3.9V or 4.2V. The output is preset at 3.4V for the G9611A, 3.3V for the G9611B/C, and 2.5V for G9611D. The reset threshold is preset at 4.2V for G9611 A/B/D and 3.9V for G9611C. 300mA Output Current, with Foldback Current Limiting High Ripple Rejection ±2% Output Accuracy ±2% Reset Threshold Accuracy Externally Programmable Reset Time Delay Generator Internal 300mA P-Channel Pass Transistor 320µA quiescent Current Thermal Overload Protection SOP 8 Package Applications CD ROM or DVD ROM „ Slim-Type CD/DVD „ DVD Player „ Ordering Information PART NUMBER G9611AP1x G9611BP1x G9611CP1x G9611DP1x MARKING G9611A G9611B G9611C G9611D REGULATOR OUTPUT VOLTAGE 3.4 3.3 3.3 2.5 RESET THRESHOLD VOLTAGE 4.2 4.2 3.9 4.2 TEMP.
