Design a Custom BoardAbout This Component
Precision programmable shunt regulator with 1% initial accuracy and adjustable output voltage from 2.5V to 36V. Offers 0.2Ω typical output impedance and 1-100mA sink current capability with low temperature drift. Ideal for on-board regulation, power supplies, and switching applications requiring stable voltage references.
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.
