GE2148 Datasheet | GTM

Description 1 . 5 A C M O S L o w D ro p o u t Vo l t a g e R eg u l a t o r The GE2148 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 GE2148 is stable with an output capacitance of 4.7 F or greater. Features Very Low Dropout Voltage Guaranteed 1.5A output Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Highly Accurate± 1.5% Low Temperature Coefficient Functional Block Diagram Applications Battery Powered Widgets Instrumentation Wireless Devices PC Peripherals Portable Electronics Package Dimensions REF.
