I haven't seen it drop below the 2.5% allowed in the spec, though, and I have drawn as much as 2.3 Amps. **Q: Is there any delay when supplying voltage till output is sent?** A: Output voltage begins to ramp up within a few micro seconds (usec) of applying input voltage but it takes a few hundred usec to reach full output voltage. The time to achieve full output depends on both the input and output voltage. I was curious so I measured a few cases. The times to reach full output voltage with a 470 Ohm load were: 10.0V in, 5.0V out: 288 usec 20.0V in, 5.0V out: 304 usec 20.0V in, 15.0V out: 570 usec 30.0V in, 15.0V out: 572 usec 30.0V in, 25.0V out: 662 usec Cheers **Q: I don't understand the limitations. Can it be used to bring 5V down to 3V?** A: It absolutely can. I have used these to convert my 12V supply into both 5V and 3.3V **Q: At 12 volts input and (say) 5 volts output, what is the quiescent (no-load) current on the 12 volt side? Thanks!** A: On my regulators the no load input current for 12V in 5V out is 7.8 mA with the output indicator LED installed. With the LED, the no-load current depends strongly on output voltage rising to 23 mA at 11V output. With the LED removed the no load input current at 12 V in 5 V out is 6.0 mA. Without the LED is independent of output voltage. ## Frequently Bought Together - BULVACK 10 Pack LM2596 DC-DC Buck Converter Step Down Module Power Supply DIP Output 1.25V-30V 3A - TUOFENG 22 awg Wire Solid Core Hookup Wires-6 Different Colored Breadboard Wires 30ft or 9m Each, 22 Gauge Electronic Wire PVC (OD: 1.60mm) Arduino Wires - Nano V3.0, Nano Board ATmega328P 5V 16M Micro-Controller Board Compatible with Arduino IDE (Nano x 3 with USB Cable) --- ## 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.no/products/151906242-10-pack-lm2596-dc-dc-buck-converter-step-down-module](https://www.desertcart.no/products/151906242-10-pack-lm2596-dc-dc-buck-converter-step-down-module) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-18*
