G9612

www.DataSheet4U.com Global Mixed-mode Technology Inc. G9612 Low-Dropout, 500mA Linear Regulator with Reset Features „ „ „ „ „ „ „ „ „ General Description The G9612 are low-dropout, linear regulator with reset function supply 3.4V, 3.3V or 2.5V output for currents up to 500mA. They are available in a 1.0W SOT 89-5L package with 0.18 inch2 copper heat sink. Typical dropouts are 560mV at 5V and 500mA. Other features include foldback current limiting and thermal overload protection. The reset function in G9612 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 G9612A, 3.3V for the G9612B/C, and 2.5V for G9612D. The reset threshold is preset at 4.2V for G9612 A/B/D and 3.9V for G9612C. 500mA Output Current, with Foldback Current Limiting High Ripple Rejection ±2% Output Accuracy ±2% Reset Threshold Accuracy Externally Programmable Reset Time Delay Generator Internal 500mA P-Channel Pass Transistor 320µA quiescent Current Thermal Overload Protection SOT89-5 Package Applications „ CD ROM or DVD ROM „ Slim-Type CD/DVD „ DVD Player Ordering Information ORDER NUMBER G9612ATEU G9612BTEU G9612CTEU G9612DTEU ORDER NUMBER REGULATOR RESET THRESHOLD MARKING (Pb free) OUTPUT VOLTAGE VOLTAGE G9612ATEUf G9612BTEUf G9612CTEUf G9612DTEUf 9612AX 9612BX 9612CX 9612DX 3.4 3.3 3.3 2.5 4.2 4.2 3.9 4.2 TEMP.
