LT3083MPDF#PBF

LT3083MPDF#PBF Description

The LT3083MPDF#PBF from Analog Devices Inc. is a high-performance, 3A adjustable linear voltage regulator designed for precision power management applications. This positive-output regulator supports an input voltage range up to 14V and delivers an adjustable output from 0V to 14V, making it highly versatile for low-voltage and precision circuits. With a low dropout voltage of 0.42V at 3A, it ensures efficient operation even under high load conditions. The device features excellent PSRR (85dB at 120Hz, decreasing to 20dB at 1MHz), minimizing noise and ripple for sensitive applications. Its ultra-low quiescent current (50.5 µA) enhances energy efficiency, while robust protection features (over-current, over-temperature, and short-circuit) ensure reliability in demanding environments.
