Design a Custom BoardAbout This Component
Precision programmable shunt regulator with adjustable output voltage from 2.5V to 36V using two external resistors. Offers 2% initial tolerance at 25°C with low temperature drift (14mV typical) and 0.2Ω output impedance. Suitable for power supply regulation, switching supplies, and industrial power applications requiring stable voltage references.
Package: SOT-363 · 6 pins
Why does this need a breakout?
SOT-363 packages are tiny surface-mount devices with 0.65mm pin pitch, making hand-soldering risky and breadboard use impossible. A breakout board breaks out the 6 pins to standard 0.1" spacing, enabling reliable prototyping of MOSFETs, transistors, and level shifters without microscopy or specialized equipment.
