G
Description
The GSC2118 of positive, linear regulator feature low ground 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.
The GSC2118 is stable with an output capacitance of 4.7 F or greater.

... External Capacitors The GSC2118 is stable with an output capacitance to ground of 4 greater. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response. Unfortunately, large value ceramic capacitors are comparatively expensive ...
