Design a Custom BoardAbout This Component
Low-dropout linear voltage regulator with 100 mA output capability and 75 µA quiescent current. Features programmable output voltage (1.25V to 29V), error output for regulation monitoring, and shutdown input for logic control. Includes internal current and thermal protection with only 50 mV dropout at light loads, ideal for battery-powered applications requiring extended runtime.
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.
