Product Description


It’s a regulator that uses switching tecnology to step-down and leveling voltage with a high efficiency and low power dissipation to disperse less power in heat.

With its adjustable voltage output from 1.25 to 25VDC and adjustable current from 0 to 2A, it’s integrates a short-circuit protection, current limiter, and overtemperature protection.

Essential to power your Arduino projects, and in applications such as high-power LEDs, in lithium charger, nickel cadmium, in solar charging nickel-hydride and batteries for wind generators.
