The G5U2188 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 G5U2188 is stable with an output capacitance of 4.7 F or greater.
