General Description
The G923 is a low supply current, high PSRR, and low
dropout linear regulator that comes in a space saving
SOT-23-5 package. The supply current at no-load is
90A. In the shutdown mode, the maximum supply
current is less than 1A. Operating voltage range of
the G923 is from 2.50V to 5.50V. The over-current
protection limit is set at 550mA typical. An over- tem-
perature protection circuit is built-in in the G923 to
prevent thermal overload. These power saving fea-
tures make the G923 ideal for use in the bat-
tery-powered applications such as notebook com-
puters, cellular phones, and PDA’s.
The G923 has two modes of operation. When the SET
pin is connected to ground, its output is a pre-set value:
1.50V~5.00V. There is no external component 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 volt-
age is then decided by the resistor ratio. The G923
comes in a space saving SOT-23-5 package.
