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 .

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! ### ⭐⭐⭐⭐⭐ Awesome *by on Reviewed in Australia 30 September 2025* Perfect item for my project...fast delivery ### ⭐⭐⭐⭐⭐ Nice little adjustable voltage regulator *by on Reviewed in the United States 21 March 2023* 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. ## Frequently Bought Together - Valefod 6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.2-35V to 1.25-30V Buck Converter DIY Power Supply Step-Down Module - ALLECIN LM358P LM358 Dual Operational Amplifier IC Om-Amp DIP-8 (Pack of 50pcs) - eBoot 6 Pack Mini MP1584EN DC-DC Buck Converter Adjustable Power Supply Module 24V to 12V 9V 5V 3V --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/309245162-6-pack-lm2596-dc-to-dc-high-efficiency-voltage-regulator](https://www.desertcart.it/products/309245162-6-pack-lm2596-dc-to-dc-high-efficiency-voltage-regulator) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-06-09*
