Description
The GQ2171 series of positive, linear regulators feature low quiescent current (50 A typ.) with low dropout
voltage and excellent PSRR, thus making them ideal for Telecommunications 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 GQ2171 is stable with an output capacitance of just extended 0.22 F or greater.
