  • VMP3111

    posted by sohman

    - easy to solder- simple output voltage selection with one resistor- high efficiency (in the optimal current range)- reasonable price- very few external components required
    The efficiency seems to be highest (over 90%) when the output current is about 700 mA
    If you have an application that needs a regulated power supply between 1 and 3.3 V with a current requirement of around 700 mA and ease of use and price is more important to you than circuit board area you will be very happy with this device. It does work for lower and higher currents too but the efficiency is lower in those scenarios.
  • Nice for voltage regulation

    posted by waynedevereaux

    Great little device for regulating voltage. Especially when some electronics require 12 v constant and turn off below a given voltage. Small potentiometer to adjust the voltage.Boosts 7v up to 12v no problems. Great for monitors and cameras.Fast shipping was here in just over a week.
    A cheaper rate would be better
    Great device,id be lost without it!
  • Good value

    Step up AND step down. Efficient, no heat loss. Indicator light when working.Screw terminals in and out, good markings +/-Accompanying spacer nuts and bolts makes installing in metal encasement a breeze. Good build quality.
    I have used this to make an emergency USB charger. With this I can connect ANY battery or combination of batteries and get a stable 5V output
    Great for variable input power sources, charge your phone from your bike dynamo, maybe? (rectify first)I have bought several, and they work as advertised
  • Very good regulator

    posted by Bunny1

    Simple and robust, very usefull. You can change trimpot by fixed resistor, there are pads to do it, and it turns into a fixed voltage regulator. Overcurrent protection. Voltage adjustment is very precise.
    Small and simple, easy to fix, possible use in many experiments and prototypes. I saw some other regulators based in LM2596 more cheap, but using bobin wih low inductance, let to experience in future.
    If you need a regulator for experiments or low production electronics, use it.
