LT3014BEDD

LT3014BEDD Description

The LT3014BEDD from Analog Devices Inc. is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision applications requiring adjustable positive output voltages. With an ultra-wide input voltage range of up to 80V, it delivers a stable output voltage adjustable from 1.22V to 60V at a modest 20mA output current. This regulator excels in efficiency, featuring a remarkably low dropout voltage of 0.57V at 20mA and a quiescent current of just 20 µA, making it ideal for power-sensitive designs. The device is housed in an 8-pin DFN package, optimized for surface-mount applications, and is classified as obsolete, though its robust performance ensures continued relevance in legacy systems.

LT3014BEDD Features

• Wide Input Range: Supports up to 80V input, accommodating high-voltage industrial and automotive applications.
• Low Dropout Voltage: 0.57V at 20mA ensures efficient operation even with small input-output differentials.
• Ultra-Low Quiescent Current: 20 µA minimizes power loss in battery-operated or always-on systems.
• High PSRR: 70dB at 120Hz provides excellent noise rejection for sensitive analog circuits.
• Advanced Protection: Includes over-current, over-temperature, and reverse-polarity protection for enhanced reliability.
• Compact Form Factor: 8-DFN package saves board space in space-constrained designs.
