General Description
The G9090 is a low supply current, low dropout linear
regulator that comes in a space saving SOT-23-5,
TSOT-23-5, SC-70-4 (SC-82 / SOT-343), SC-70-5
(SOT-353), TDFN2X2-6 and TDFN2X2-8 package. The
supply current at no-load is 100µA. In the shutdown
mode, the maximum supply current is less than 1µA.
The over-current protection limit is set at 430mA typi-
cal. An overtemperature protection circuit is built-in in
the G9090 to prevent thermal overload. These power
saving features make the G9090 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 G9090
is specifically designed to employ ceramic output ca-
pacitors. The G9090 comes in a space saving
SOT-23-5, TSOT-23-5, SC-70-4(SC-82/SOT-343),
SC-70-5 (SOT-353), TDFN2X2-6 and TDFN2X2-8
package.
