  • Name: adjustable linear regulator
  • Output current: 1.5A (minimum), 2.2A (typical)
  • The input and output voltage difference (VIVO): 40Vdc (max)
  • Output adjustable voltage range: 1.2 ~ 37V
  • Working temperature: 55 ~ C to +150 ~ C
  • Current output: 1.5A
  • Voltage input: 4.2 ~ 40 V
  • Working temperature: 0 ~ C ~ 125 degrees C
  • Characteristic frequency: 100 (MHz)
  • Module size: 35.6 (mm) x16.8 (mm)
  • Input mode: VIN input positive stage, GND input negative pole
  • Output mode: VOUT output positive stage, GND output negative pole
  • Max output current: max output current =3/ (input voltage output voltage)
  • Buyers need to know because it is linear, so the efficiency is not high, in order to improve the efficiency, the best input and output 3V differential pressure. But the input and output the maximum voltage difference is best not more than 30V, namely: input - output is less than or equal to 30V, otherwise it is very easy to burn module.
  • Because it is a linear buck DC-DC circuit, the input voltage need to be higher than the output voltage of 3V pressure difference, in order to ensure the stability of output voltage.
  • Input voltage: 40V-4.5V (maximum maximum limit of the shop can be up to 40V),
  • Regulation: first correct answer power input (40-4.5 between) and then watch monitors the output voltage and regulating potentiometer (general clockwise turn boost, inverse turn Buck)
