General Description
The G9091 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), TDFN1.6X1.6-6, 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 typical. An overtemperature protection cir-
cuit is built-in in the G9091 to prevent thermal overload.
These power saving features make the G9091 ideal
for use in the battery-powered applications such as
notebook computers, cellular phones, and PDA’s.
These devices feature a shutdown function and are
offered in active low with auto discharge. The G9091
is specifically designed to employ ceramic output ca-
pacitors. The G9091 comes in a space saving
SOT-23-5, TSOT-23-5, SC-70-4(SC-82/SOT-343),
SC-70-5 (SOT-353), TDFN1.6X1.6-6, TDFN2X2-6 and
TDFN2X2-8 package.
