This is a DC/DC step-down voltage regulator that converts input voltage between 4.5V and 16V into a smaller voltage between 1V and 12V, capable of driving a 1.5A load with excellent line and load regulation. ![enter image description here][1] In some projects, you might need different voltages (1-12V) for your devices. Without this kind of DC power source, you’ll find it time-consuming to buy a new one. The delay of project is so annoying. No worries! This module can accelerate prototyping, because you can get the voltage you need (such as 1.2V,1.8V,3.3V, 5V and 9V) as easy as blinking eyes. Features Wide Output Voltage Range Ensured 1.5A Output Load Current Input Voltage Range Up to 16V Excellent Line and Load Regulation Low Power Standby Mode Precise potentiometer for voltage adjustment Thermal Shutdown and over-current protection Specification Input Voltage: 4.5-16V Output Voltage: 1V - 12VDC Heating consumption: 0.5-1200mW Load resistance: can adjust Max.
