GSC2129
Description
C M O S L o w D r o p o u t Vo l t a g e R e g u l a t o r
The GSC2129 series of positive, linear regulators feature low quiescent current (45 A typ.) with low dropout
voltage, making them ideal for battery applications.
Output voltages are set at the factory and trimmed to 1.5% accuracy.
These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under
the “Worst” of operating conditions.
In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground.
The GSC2129 is stable with an output capacitance of 4.7 F or greater.
