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.
