Fixed 1.8V LDO for noise-sensitive rails
The Analog Devices LT1763IS8-1.8#PBF is a single-output positive linear regulator delivering a fixed 1.8V at up to 500mA from an input rail that can go as high as 20V. It is built for applications where clean, low-noise power is needed — think analog front-end supplies, sensor bias, or post-regulation after a switching converter. The part includes over-current, over-temperature, and reverse-polarity protection, which saves you from adding external supervisory components on the board. With an industrial temperature range of -40°C to 125°C, it suits outdoor telecom, factory automation, and under-hood automotive environments where the ambient can swing hard.
Active production, no end-of-life concern
The LT1763IS8-1.8#PBF carries an active lifecycle status from Analog Devices. For a BOM line that needs a stable supply through the next several years, this part is a safe call — no need to qualify a second source for continuity reasons alone.
Package and footprint notes
The part comes in an 8-lead SOIC package (0.154" body width, 3.90 mm) with a surface-mount footprint. The supplier device package is designated 8-SO. The enable control pin lets you sequence the rail on and off without a separate load switch.
