Product details

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.

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.

Frequently asked questions

What is the output voltage of LT1763IS8-1.8#PBF?

Ensures the regulator matches the required fixed output voltage for the application.

What is the maximum input voltage for LT1763IS8-1.8#PBF?

Critical to avoid exceeding the absolute maximum rating and damaging the device.

Where can I buy LT1763IS8-1.8#PBF with immediate stock?

Sourcing buyers need to verify availability to support production without delays.

What are the equivalent or replacement parts for LT1763IS8-1.8#PBF?

Designers and buyers need alternatives for second sourcing or when the part is unavailable.

Is LT1763IS8-1.8#PBF obsolete or still in production?

Lifecycle status affects long-term availability and risk of redesign for production boards.

What is the dropout voltage at 500mA for LT1763IS8-1.8#PBF?

Determines headroom requirement to maintain regulation in low input voltage scenarios.
