General Description
The G9001 is a low supply current, low dropout linear
regulator. The supply current at no-load is 100µA. In
the shutdown mode, the maximum supply current is
less than 1µA. Output current minimum limit is 500mA,
and over-current protection limit is set at 860mA typi-
cal. An overtemperature protection circuit is built-in in
the G9001 to prevent thermal overload. These power
saving features make the G9001 ideal for use in the
battery-powered applications such as notebook com-
puters, cellular phones, and PDA’s.
These devices feature a shutdown function and are
offered in active low with auto discharge. The G9001
is specifically designed to employ ceramic output ca-
pacitors. The G9001 comes in a space saving SOT-89,
SOT-23, SOT-23-5 and TSOT-23-5 package.
