That means one IC can generate four separate supply rails — say 3.3V, 2.5V, 1.8V, and 1.2V — from a single input voltage between 4V and 36V. The built-in sequencer controls the power-up order of the outputs, which is critical for FPGAs, SoCs, or mixed-signal ASICs that need core voltage before I/O or analog rails. The three buck converters are rated for 2.7A, 1.8A, and 1.8A respectively; the LDO handles lower-current analog or standby rails. Switching frequency is fixed between 900kHz and 1.1MHz, keeping the magnetics small. ## Temperature range and package — what they mean on site The 38-WFQFN with exposed pad (5x7 mm) helps pull heat out through the PCB copper. The package is surface-mount only, so field swaps are possible with a hot-air rework tool, but the exposed pad makes alignment critical — a misaligned pad can short the die flag to a nearby pin. ## Sourcing and lifecycle — still in active production Analog Devices lists the LT3507AEUHF#TRPBF as Active — no end-of-life notice, no last-time buy window looming. That means you can design it in today and expect supply for the foreseeable future. Available in Tape & Reel (TR) or Cut Tape (CT) options, which suits both automated pick-and-place assembly and prototype runs.","metaTitle":"LT3507AEUHF#TRPBF Quad Buck/LDO Regulator – Analog Devices","metaDescription":"LT3507AEUHF#TRPBF quad-output regulator: 3 buck converters + 1 LDO, 4V-36V input, -40°C to 125°C, 38-QFN.
