## Overview

The 3.3V Regulator Mini Reducer is a compact and efficient buck converter module designed to provide a stable 3.3V output from a wide input range of 4.5V to 24V. With a maximum output current of 1.8A and low ripple, this module is perfect for various electronic applications. Each package includes 5 units, making it an ideal choice for hobbyists and professionals alike.

## Description

The volume is very small, the input voltage is 4.75-23V The maximum output current is 1.8A, preferably within 1.5A Please pay attention to the positive and negative poles when using this module, the positive and negative pole marks are on the back of the circuit board If you use high current for a long time, please do a good job of heat dissipation, the working temperature is -40℃-85℃ Package: 5pcs buck module

Review: Battery Replacement - I used this to make a power supply to replace 2 - 1.5 volt batteries. I connected it to a USB power cube. Works great. Voltage output is 3.3VDC.
Review: Work great and hold at about 3.2 3.3 volts with no problems - I bought these switching type 3.3 regulators to replace some 3.3v linear regulators that just didn't cut it and kept blowing up. So far these have done their job well and don't get hot like the linear versions.

## Features

- Very small size, length, width and height are 17*11*3.6mm，Input: 4.5V-24V,Output: 3.3V,
- The maximum output current can reach 1.8A, when the output current is 1.5A, the output voltage is 3V
- Output ripple: less than 30 mV; Switching frequency: 1.5 MHz (highest), typically 1 MHz
- When using this module with an inductive load, please pay attention to the protection of the current in the rear stage. For example, when using a steering gear or a motor, a large ripple may be generated, which may affect the chips in the rear stage circuit. You can add Zener and capacitor for protection
- Package: 5PCS 3.3V Buck Module

### ⭐⭐⭐⭐⭐ Battery Replacement
*by G***T on July 14, 2024*

### ⭐⭐⭐⭐⭐ Work great and hold at about 3.2 3.3 volts with no problems
*by D***T on June 30, 2024*

I bought these switching type 3.3 regulators to replace some 3.3v linear regulators that just didn't cut it and kept blowing up. So far these have done their job well and don't get hot like the linear versions.

### ⭐⭐⭐⭐ QC Issue, but otherwise fine
*by D***Y on July 20, 2025*

Mixed report. 4ea worked fine, but 1ea a resistor fell off in transit (poorly soldered) and was floating free in the bag. Quiescent current draw is 7ma. BTW: Outside of my expertise, but worth mentioning just in case the following is uncommon. If you disconnect supply power to the input of this module, any power source (e.g. a 3.2v backup coin battery, or a MCU programmer) that is connected to the output side of this module will meet a 300mA load. (This may be common to all buck converters, worth checking into)
