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 GQ2141 of positive, linear regulator feature low quiescent current (50 A typ.) with low dropout voltage and
excellent PSRR, thus making them ideal for Telecommunications and other battery applications.
The GQ2141’s output voltage can be adjusted with an external resister divider.
These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under
the “Worst” of operating conditions.
As an additional feature, the GQ2141 is stable with an output capacitance of just extended 0.22 F or greater.
