AC/DC Power Adapter 12v 1.5A


12V Step-Up Voltage Regulator

12V Step-Down Voltage Regulator

Quick Overview

12V Step-Down Voltage Regulator by Pololu
In Stock


This micro sized step-down voltage regulator is perfect for supplying 12v power (from a higher voltage source like 4s or 5s Lipo) to your FPV gear that needs specifically 12v range.  Power 12v flight cameras, LED lights or other gear that can only run on 12v.

The compact (0.4″ × 0.5″) D24V6F12 switching step-down (or buck) voltage regulator takes an input voltage between 15 V and 42 V and efficiently reduces it to 12 V while allowing for a maximum output current of 600 mA. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.


  • Input voltage: [output voltage + dropout voltage] to 42 V
  • Fixed 12 V output with 4% accuracy
  • Maximum output current:  600 mA
  • 1.25 MHz switching frequency
  • 2 mA typical no-load quiescent current (20 μA typical quiescent current with SHDN = LOW)
  • Integrated over-temperature and over-current shutoff
  • Small size: 0.5″ × 0.4″ × 0.1″ (13 mm × 10 mm × 3 mm)

Typical Efficiency and Output Current

The efficiency of a voltage regulator, defined as (Power out)/(Power in), is an important measure of its performance, especially when battery life or heat are concerns. As shown in the graphs below, this switching regulator typically has an efficiency of 80% to 90%.

  1. Very nice review by Bryan on 10/1/2015

    Functions as described. I put 14v`16v in and ran my gimbal and Vtx out. Checked the voltage out with a multimeter, I got 11.91v out. This voltage regulator is very efficient.

  2. Does the trick review by Samuel on 5/10/2015

    Needed a voltage regulator to drive leds on my QAV250 running 4s. It's just one of those parts that you solder into the circuit, cover in shrink tubing, and completely forget about. It works as advertised and is a simple fix for an inconvenient problem. My thanks goes to fellow reviewer Nick for suggesting that the SHDN pin be tied to VIN for stable operation.

  3. Important: Bridge SHDN to VIN review by Nick on 12/21/2014

    Based on the original product page from Pololu : http://www.pololu.com/product/2109

    You should bridge the SHDN pin to the VIN pin to make sure the board does not unpredicably cut-out on you. From the product page:

    "The SHDN pin can be driven low (under 0.3 V) to turn off the output and put the board into a low-power state that typically draws 20 μA, and it can be driven high (above 2.3 V) to enable the board. If you do not need to use the shutdown feature, the SHDN pin can be directly connected to VIN to permanently enable the board. You should not leave this pin disconnected as this can result in unpredictable behavior."
