GQ2181
GQ2181 is CMOS POSITIVE VOLTAGE REGULATOR manufactured by GTM.
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 GQ2181 series of positive, linear regulators feature low quiescent current (50 A typ.) with low dropout voltage and excellent PSRR, thus making them ideal for Telemunications and other battery applications. 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 GQ2181 is stable with an output capacitance of just extended 0.22 F or greater.
