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 V
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.
