General Description
The G913 is a low supply current, low dropout linear
regulator that comes in a space saving 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 of the G913 is from
2.5V to 5.5V. The over-current protection limit is set at
550mA typical. An over-temperature protection circuit
is built-in in the G913 to prevent thermal overload.
These power saving features make the G913 ideal for
use in the battery-powered applications such as note-
book computers, 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:
1.5V~4.7V (interval =100mV), 2.84V, 3.15V, and
4.75V. There is no external component needed to de-
cide 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 resistor ratio. The G913 comes in
a space saving SOT-23-5 package.
