LT3085EDCB#TRMPBF

Product Overview

The Analog Devices Inc. LT3085EDCB#TRMPBF is a positive adjustable linear voltage regulator IC with one output and a 500 mA output current rating. It is offered in a 6-DFN (2x3) surface-mount package with an exposed pad. The device supports input voltages up to 36 V and adjustable output voltages from 0 V to 36 V, with a maximum dropout of 0.45 V at 500 mA. Quiescent current is specified at 10.1 µA, and supply current is limited to 1 mA. Protection features include over current, over temperature, and short circuit. The operating temperature range is -40°C to 125°C.

Key Features

• Positive adjustable output with one regulator and 500 mA output current
• Input voltage maximum of 36 V and output range of 0 V to 36 V
• Maximum dropout of 0.45 V at 500 mA
• Quiescent current of 10.1 µA and maximum supply current of 1 mA
• PSRR specified as 90 dB to 20 dB from 120 Hz to 1 MHz
• Over current, over temperature, and short circuit protection features
• 6-WFDFN exposed pad, 6-DFN (2x3), surface-mount package for -40°C to 125°C operation

Applications

• Generation of adjustable positive supply rails in battery-powered and fixed-supply electronic assemblies
• Voltage regulation for mixed-signal and digital subsystems operating from inputs up to 36 V
• Power conditioning for analog, sensor, and communication front-end circuits where linear regulation is required

Design & Procurement Notes

When selecting the LT3085EDCB#TRMPBF, confirm that the input voltage does not exceed 36 V and that the chosen output voltage is within 0 V to 36 V while maintaining adequate headroom above the 0.45 V maximum dropout at 500 mA. The 10.1 µA quiescent current and 1 mA maximum supply current should be evaluated against total system power budgets. The 90 dB to 20 dB PSRR over 120 Hz to 1 MHz can guide placement relative to sensitive analog or communication circuitry. The 6-WFDFN exposed pad and 6-DFN (2x3) surface-mount package require PCB footprint and exposed-pad layout considerations. Over current, over temperature, and short circuit protection should be coordinated with load requirements and input supply behavior, and the -40°C to 125°C operating range should be checked against the final assembly environment.
