Design a Custom BoardAbout This Component
Adjustable positive linear voltage regulator delivering up to 100 mA with selectable output from 1.2 to 37 V using external resistive divider. Features 0.01% line regulation and 0.1% load regulation with built-in thermal overload and short-circuit protection. Ideal for low-current power supply applications requiring programmable voltage output.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
