## Overview

This 10-pack of DORHEA 5V regulator modules offers a versatile DC input range of 4.5-24V and adjustable output from 0.8 to 17V, with fixed voltage presets including 5V and 12V. Each compact buck converter supports up to 3A output current with high efficiency (up to 97.5%) and features an integrated enable port for convenient power control. Designed for professional-grade projects, these mini voltage reducers combine stable performance, low ripple, and industrial temperature tolerance in a space-saving form factor.

## Description

Product description 5V Regulator Module Input Voltage: DC 4.5-24V Output Voltage: Integrated adjustable and fixed output Adjustable range is 0.8-17V, fixed output are 1.8V, 2.5V, 3.3V, 5V, 9V, 12V that can be chosen on the back side. Output Current: 3A max (please enhance cooling work when it is full load); When real tested input 12V and output is 1.5A, no need to add special system. Conversion Efficiency: 97.5% (6.5V to 5V, 0.7A) Temperature rising range at full load: 40℃ Static Current: 0.85mA Dynamic Response Speed: 5% 200uS Switch Frequency: 500KHz Output Ripple: 20mV(12V to 5V, 3A) 20M width Operating Temperature: -40℃ ~ +85℃(Industrial class) 5V Buck Converter Board Output Over-voltage Protection: no Output Short-circuit Protection: yes, please don’t keep making it short-circuit. Output Reverse Connection Protection: no Enable Function Control: yes Mini Voltage Reducer Low electric level will stop working when high electric level is working. High electric level is 2-5V, low electric level is 0V or so. Wiring Method: soldering Input Method: soldering Output Method: soldering or pins Welding Hole Spacing: 2.54mm Package includes 10 X Mini 5V regulators module

Review: Bought 10 of these and every one of them actually worked ! - Bought three different styles of step down regulators in last order . The entire lots of the first two types were rejected as defective and completely non functional . These little 5v step down regulators however work fine . Out of 10 units the output voltage from the same source (battery) ranged from 5.07 thru 5.21 volts . There is some variation in output voltage but .14vdc total spread is not fantastic but also not terrible either . Can't speak for longevity , noise , ripple or current capacity at this point . PCB's appear well soldered , can't complain for the price these days !
Review: 50% defect rate!! - High defect rate in these converters. Approximately 50% of the boards I tested were defective and could not output a suitable voltage in line with the description (Example 12volts in, could only get 1.5 to 2v out). Many had potentiometers that were seemed to 'jump around' and couldn't hold a consistent voltage. They were shipped in regular polyethylene bags without anti-static packaging. These seem cheap and a good value, until you realize you've wasted time with bad boards and have to sort the bad from good. Additionally, the boards were of inconsistent dimensions--they came with 2 different widths. this made packaging them into a project more challenging. The only reason I kept these were I ran out of time.

## Features

- Voltage regulator input voltage range is DC 4.5-24V, adjustable range is 0.8-17V, fixed output are 1.8V, 2.5V, 3.3V, 5V, 9V, 12V that can be chosen on the back side. Max output current: 3A (please enhance cooling work when it is full load); If the actual test input is 12V and output is 1.5A, no other system is required.
- Adjustable and fixed voltage output, you can get fixed output voltage by soldering the pot on the board of regulator module; You can also adjust the fixed output voltage by potentiometer as you needed. Default output is adjustable. Note: if you need to fix the output voltage, use a knife to cut the wires in the red circle in the picture, and then connect the pads with solder at the voltage you need.
- High efficiency and super compact size, high frequency and low ripple, stable working performance, wide range of applications, this 12v to 5v converter will be a good component for fixing work.
- Integrated enable port defaults the working mode and it will be off when it is at low electric level off, which bring a great convenience for users. NOTE: This 5v step down converter is really tiny, each unit is smaller than half a one-dollar coin.
- Convenient to use, integrated enable port of the regulator board defaults to working mode and will be closed when it is at low electric level off, and with ultra-low quiescent current, quiescent current is 0.85 mA; It can be connected to the car battery without a switch, cigarette lighter cord or the ACC power cord.
