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 de-
termined by external capacitor. The reset output is
active low open-drain output. The detection thresh-
old 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.
