Design a Custom BoardAbout This Component
Adjustable three-terminal positive voltage regulator delivering over 100 mA with output voltage range from 1.2 V to 37 V. Requires only two external resistors for voltage setting and features internal current limiting, thermal shutdown, and safe-area compensation. Suitable for local on-card regulation, programmable supplies, and precision current source applications.
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.
