General Description
The G914 is a low supply current, low dropout linear
regulator that comes in a space saving SOT23-5 pack-
age. The supply current at no-load is 52µA. In the
shutdown mode, the maximum supply current is less
than 1µA. Operating voltage range of the G914 is from
2.5V to 5.5V. The over-current protection limit is set at
370mA typical and 150mA minimum. An overtem-
perature protection circuit is built-in in the G914 to
prevent thermal overload. These power saving fea-
tures make the G914 ideal for use in the bat-
tery-powered applications such as notebook com-
puters, cellular phones, and PDA’s.
The G914 is a adjustable output version in a small
SOT 23-5 package.

Layout Guide
An input capacitance of ≅ 1µF is required between the
G914 input pin and ground (the amount of the capaci-
tance may be increased without limit), This capacitor
must be located a distance of not more than 1cm from
the input and return to a clean analog ground.
Input capacitor can filter out the input voltage spike
caused by the surge current due to the inductive effect
of the package pin and the printed circuit board’s
routing wire. Otherwise, the actual voltage at the IN
pin may exceed the absolute maximum rating.
The output capacitor also must be located a distance
of not more than 1cm from output to a clean analog
ground. Because it can filter out the output spike
caused by the surge current due to the inductive effect
of the package pin and the printed circuit board’s
routing wire. Figure 3 is suggested PCB layout of
G914.

*Distance between pin & capacitor must no more than 1cm
