5 5 A 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 G5U2189 of positive, linear regulators 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 G5U2189 is stable with an output capacitance of 4.
7 F or greater.
