General Description
The G913 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 55µA. In the
shutdown mode, the maximum supply current is less
than 1µA. Operating voltage range of the G913 is from
2.5V to 5.5V. The over-current protection limit is set at
250mA typical and 150mA minimum. An overtem-
perature protection circuit is built-in in the G913 to
prevent thermal overload. These power saving fea-
tures make the G913 ideal for use in the bat-
tery-powered applications such as notebook com-
puters, cellular phones, and PDA’s.
The G913 has two modes of operation. When the SET
pin is connected to ground, its output is a pre-set
value: 2.84V for G913A, 3.15V for G913B, and 3.30V
for G913C, and 3.00V for G913D. There is no external
components needed to decide the output voltage.
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 decided by the re-
sistor ratio. The G913 comes in a space saving
SOT23-5 package.
