Design a Custom BoardAbout This Component
Precision programmable shunt regulator with 1% initial tolerance and adjustable output voltage from 2.5V to 36V. Offers 0.2Ω typical output impedance, 1-100mA sink capability, and stable operation across -40°C to 125°C. Ideal for switching power supplies, on-board regulation, and precision voltage reference applications.
Package: SOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
