Input voltage range: 3.6V-36V.Output voltage range: negative 1.5V to negative 36V. Output voltage regulation characteristics; load regulation rate of less than 5%.Output current. The IC of the module is 1.5A internal switch, but for safety and heat considerations, it is recommended that the load power of this module is less than 0.5W. That is, the output negative 5V, the load within 100MA, the proposed 50MA.Other parameters:Using single-chip embedded technology.Input positive voltage, output negative voltage.Easy to operate, you can adjust the output voltage through the potentiometer.The module is small, easy to carry and use a variety of occasions
