Design a Custom BoardAbout This Component
Precision adjustable shunt regulator with programmable output voltage from 1.24V to 16V. The B-series variant offers ±0.5% reference accuracy at 25°C and ±1.0% over industrial temperature range. Features low dynamic impedance of 0.20Ω across 100µA to 20mA operating range. Commonly used as precision zener replacement, power supply error amplifier, and voltage/current reference in analog and digital circuits.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
