Stable 12V Power for Embedded Builds

The 12V, 2.4A Step-Down Voltage Regulator D36V28F12 is a compact switching regulator for projects that need a lower and more stable DC rail from a higher input source.

It is a strong fit for robots, control boxes, battery-powered builds, and embedded systems that need efficient power conversion with less heat than a linear regulator.

Important: Choose a regulator based on your full input-voltage range, startup current, thermal limits, and required headroom. Real output current depends on input voltage, airflow, and temperature.

Why you'll love it

  • Input range: 12.9V to 50V (minimum depends on dropout vs load)
  • Output: 12V with 4% accuracy
  • Current capability: listed typical max output current is 2.4A at 36V in ; continuous current depends on VIN and thermal dissipation
  • Typical efficiency 90–95% (VIN/load dependent)
  • Switching frequency ~ 500kHz under heavy loads
  • Power-save mode keeps operation ultrasonic (>20kHz) while improving light-load efficiency

What you can build

Great for powering 5V or 12V rails in robots, controllers, sensor hubs, SBC projects, vehicle electronics, and custom battery systems.

Frequently Asked Questions

Can I power a microcontroller with this?
Yes, if the regulator’s output voltage and current match your controller and all attached loads.
Will it run cool at full load?
It depends on input voltage, airflow, and load current. Check thermal limits in the official Pololu resources.
Is this better than a linear regulator?
For many builds, yes. Switching regulators are usually more efficient and waste less heat.
