Features
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 &
SC-70-5(SOT-353) 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.

Over-Temperature Protection and Short-Circuit
Protection
Fixed Mode: 1.20V~5.00V (G916-XXX)
Adjustable Mode: from 1.25V to 5.50V (G916)
Max. Supply Current in Shutdown Mode < 1µA
Low Output Noise at 28µVRMS with bypass Capacitor
Stable with low cost ceramic capacitors
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 external 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.
