Shunt Regulators

Shunt regulators provide a simple, low‑cost way to clamp voltage spikes and protect power supplies in motor‑driven or other high‑current circuits. By diverting excess energy through a precisely‑rated shunt resistor, they maintain a stable voltage without requiring complex feedback loops. Available in a range of fixed set‑points and adjustable versions, they suit projects from small‑scale sensor rigs to larger robotic actuators. Key attributes include power‑handling capability, shunt resistance value, and the number of surface‑mount resistors used to share dissipation. Their compact PCB footprint and straightforward wiring make them easy to integrate alongside existing supply rails, while their robust construction ensures reliable operation under repeated transient events.
