Review: I built a Max97220 headphone amplifier/line driver/preamplifier and to prevent it ever being destroyed by overpowering the 5 volts DC limit, I used this power supply regulator. I blew up the first one with reverse polarity so I added two 1N4004 diodes to the front to prevent reverse polarity destruction. The diodes drop a few millivolts but better safe than sorry. Works like a charm. The resistor in the photo was just a dummy load for test and setup but I ended up leaving a 10k ohm resistor in parallel with the MAX97220 supply VCC to maintain an idle current of 0.5mA on the 2596 board. It also has an LED in series with a 1k ohm resistor drawing another 3mA. The 1N4004s turned the LM2596/Max97220 combination into a radio receiver so I connected the audio ground on the negative terminal of the LM2596 PCB and it ran 100% perfect and silent. Great little board!

## Questions & Answers

**Q: Is the output a percentage of the input, or a constant?  If I have 20 v in, adjust to 5v out;  input goes to 30v will output be 5v or 7.5v?**
A: Output voltage is set by the variable resistor and stays independent of the input voltage (
as long as the input voltage stays a few volts above the output voltage). If the input voltage dips, the output voltage will also dip.

**Q: What are the dimensions of this voltage regulator?**
A: 43 x 21 x 12 mm using caliper on actual product.

**Q: Is there any datasheet / CAD model that shows mounting hole dimensions and location of the mounting holes?**
A: None I know of just trace it out with standoff mounted in your project case and use dremel dril bit kit according to thread hole size. 
Good-luck.

**Q: Does anyone have the dimensions of mounting holes, and voltage input/output locations?**
A: Mounting holes will work with standoff kits on amazon nylon or etal with screws .

So far, so good. I bought a six pack of these voltage regulators. The first one I hooked up I messed up and reversed the input voltage. This immediately smoked the regulator; so beware that there is no reverse voltage protection on the input. This was completely my mistake, and not an issue with the product. I hooked the second voltage regulator up to my test setup, and it worked great. I used a 32VDC power supply salvaged from an old HP printer as the input supply. I tested the output with a high power 2kohm resistor. I was able to adjust the output voltage to a steady 12.00 volts according to my digital multimeter. The input voltage remained approximately the same as before I connected the output load. Then I switched the load to a small DC motor with a gear train attached. The voltage output remained very stable at +/- 0.01 volts from the 12.00 volts I had set with the resister test. Overall I'd say these are inexpensive and very nice little voltage regulators, and a good value for the money. I intend to add a little voltage meter and build a little benchtop power supply with this one.
