  • 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.
  • 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.
  • Ok unit for the money

    posted by buddax

    Work as expected. No real problems so far.The unit can obviously also be used as an DC/DC transformer if you bypass the rectifier and use a DC power source.
    Remember that the bottom side has exposed solder points! So be aware where you place the unit while the power is on.
    Seems like a fair deal if it don't burn out on me anytime soon.
  • OK, but not for solar panel

    posted by Alexketto

    Excuse me, for my english.Good construction. No other parts needed. Fully adjustable output voltage within the specified value.
    If you would solve the use of solar panels, it would be a very nice gadget.
    Good, goog, but the Solar Power Supply?
  • Switching Regulator

    posted by Logsplitter

    A simple device, no external components required. Output ripple is very low, as is heat as full output. No heatsink necessary even at continuous full output, (with 15 volts supply voltage).
    The regulators can be combined with steering diodes to increase output current. The ripple does not appear to increase even when combining the output of 3 regulators.
    An excellent stand alone regulator, especially for a USB power source. Have used more than a dozen for automotive cellphone chargers without a single failure
