GJ2148
Description
1 . 5 A C M O S L o w D ro p o u t Vo l t ag e R e g u l a t o r
The GJ2148 series of positive, linear regulators feature low quiescent current (45 A typ.) with low dropout voltage, making them ideal for battery applications. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the “Worst” of operating conditions. The GJ2148 is stable with an output capaci.
