5 x mini 5v regulator
DROK 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. Output current is 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.
Output integrated adjustable and fixed voltage, you can get fixed output voltage by soldering the pot on the board. If the fixed output voltage is not what you want, you can adjust it by potentiometer.
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.
Strong and high quality construction: imported potentiometer and 3A current chip, high current shielded inductors and MLCC solid capacitance with long service life.
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.
