Design a Custom BoardAbout This Component
Adjustable precision shunt regulator with 0.5% voltage tolerance and 2.5V reference. Programmable output from 2.5V to 36V with low temperature coefficient (20ppm/°C typical), 0.15Ω dynamic output resistance, and sink current capacity to 100mA. Ideal for switching power supplies, chargers, and precision voltage references.
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.
