General Description
The G916 series is a low supply current, high PSRR,
low noise, and low dropout linear regulator that comes
in a space saving TSOT-23-5, SOT-23-5 package.
The supply current at no-load is 90µA. In the shutdown
mode, the maximum supply current is less than 1µA.
Operating voltage range is from 2.5V to 6.0V. 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. These power
saving features make the G916 series ideal for use in
the battery-powered applications such as notebook
computers, cellular phones, and PDA’s.
The G916 has two modes of operation. When the SET
pin is connected to ground, its output is a pre-set value:
3.3V. There is no external component needed. When an
output other than the preset value is needed, two ex-
ternal resistors should be used as a voltage divider. The
output voltage is then adjusted by the resistor ratio.
G916-XXX is with fixed-mode output. The output voltage
range is from 1.2V to 5.0V.

Limits is 100% production tested at TA= +25°C. Low duty pulse techniques are used during test to maintain junc-
tion temperature as close to ambient as possible.
Guaranteed by line regulation test.
Adjustable mode only.
Not tested. For design purposes, the current limit should be considered 400mA minimum to 650mA maximum.
The dropout voltage is defined as (VIN-VOUT) when VOUT is 100mV below the target value of VOUT. The performance of
every G916 part, see “Typical Performance Characteristics”.
