Stable with low cost ceramic capacitors
General Description
The G914X is a low supply current, high PSRR low
dropout linear regulator that comes in a space saving
SOT-23-5 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 pro-
tection limit is set at 500mA typical and 400mA mini-
mum. 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
computers, cellular phones, and PDA’s.
