General Description
The G9092 is a dual, low supply current, low dropout
linear regulator that comes in a space saving
SOT-23-6, TSOT-23-6, TDFN2X2-8 and TDFN3X3-8
package. The supply current at no-load is 200µA. In
the shutdown mode, the maximum supply current is
less than 1µA. Output voltage range of the G9092 is
from 1.2V to 3.3V. The over-current protection limit is
set at 400mA typical. An over-temperature protection
circuit is built-in in the G9092 to prevent thermal over-
load. These power saving features make the G9092
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 G9092
comes in a space saving SOT-23-6, TSOT-23-6,
TDFN2X2-8 and TDFN3X3-8 package.
