General Description
The G914X is a low supply current, low dropout linear
regulator that comes in a space saving SOT23-5
package. 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 G914X is
from 2.5V to 5.5V. The over-current protection limit is
set at 500mA typical and 400mA minimum. An
over-temperature protection circuit is built-in in the
G914X to prevent thermal overload. These power
saving features make the G914X ideal for use in the
battery-powered applications such as notebook com-
puters, cellular phones, and PDA’s.
