GQ2131
Description
C M O S P o s i t i v e Vo l t a g e R e g u l a t o r
The GQ2131 is a fixed 1.2V of positive, linear regulators feature low quiescent current (60 A typ.) with low
dropout voltage, making them ideal for battery applications.
This rugged device has both Thermal Shutdown, and Current Fold-back to prevent device failure under the
“Worst” of operating conditions.
An additional feature is a “Power Good” detector, which pulls low when the output is out of regulation.
The GQ2131 is stable with an output capacitance of 2.2 F or greater.
