Description

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.
