General Description
The G917 series is a low supply current, high PSRR,
low noise, and low dropout linear regulator that comes
in a space saving SOT-23-5 package. The supply
current at no-load is 100µA. In the shutdown mode,
the maximum supply current is less than 1µA. Operat-
ing voltage range is from 2.5V to 6.0V. The
over-current protection limit is set at 750mA typical. An
over- temperature protection circuit is built-in in the
Device to prevent thermal overload. These power
saving features make the G917 series ideal for use in
the battery-powered applications such as notebook
computers, cellular phones, and PDA’s.
The G917 has two modes of operation. When the SET
pin is connected to ground, its output is a pre-set value:
3.3V. There is no external component needed. When an
output other than the preset value is needed, two ex-
ternal resistors should be used as a voltage divider. The
output voltage is then adjusted by the resistor ratio.
