General Description
The G9161 series is a low supply current, high PSRR,
and low dropout linear regulator that comes in a
SOT-89, SOT-223, TO-252 and SOP-8 with Power
PAD package. The supply current at no-load is 90µA.
Operating voltage range is from 2.50V to 5.50V. The
over-current protection limit is set at 550mA typical. An
over- temperature protection circuit is built-in in the
Device to prevent thermal overload.
The output voltage range is from 1.2V to 5.0V.
