G9294
Global Mixed-mode Technology Inc.
Dual, 300mA Low-Dropout Linear Regulators
Features
General Description
„
The G9294 is a dual, low supply current, low dropout
linear regulator that comes in a space saving
TSOT-23-6 & TDFN1.6X1.6-6 and TDFN2X2-8 package. The supply current at no-load is 60µA. In the
shutdown mode, the maximum supply current is less
than 1µA. Output voltage range of the G9294 is from
1.2V to 3.3V. The over-current protection limit is set at
500mA typical. An over-temperature protection circuit
is built-in in the G9294 to prevent thermal overload.
These power saving features make the G9294 ideal
for use in the battery-powered applications such as
notebook computers, cellular phones, and PDA’s.
