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!

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 .

Great little board! ### ⭐⭐⭐⭐⭐ Awesome *by K***L on 30 September 2025* Perfect item for my project...fast delivery ### ⭐⭐⭐⭐⭐ Nice little adjustable voltage regulator *by A***A on 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.com.sa/products/309245162-6-pack-lm2596-dc-to-dc-high-efficiency-voltage-regulator](https://www.desertcart.com.sa/products/309245162-6-pack-lm2596-dc-to-dc-high-efficiency-voltage-regulator) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-06-09*
