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.
