G
Description
The GSC2127 series of positive, linear regulators feature low quiescent current (45 A typ.) with low dropout
voltage, making then 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.
An additional feature is a “Power Good” detector, which pulls low when the output is out of regulation.
The GSC2127 is stable with an output capacitance of 4.7 F or greater.
