DC\/AC To DC LM317 Power Continuous Adjustable Voltage Regulator 1.25V-37V With Protection Description: Output voltage does not exceed Input voltage. This is buck board， not boost board. Output short-circuit protection Adjust pipe security protection Overcurrent， overheating protection Specification: DC input voltage: 5-35V AC input voltage: 6-24V Output voltage: 1.25V-37V adjustable Output current: 1A Ripple rejection ratio: 80dB Typical load regulation: 0.1% Typical linear regulation: 0.01% Note: Since the within LM317 is linear voltage regulator， power consumption are high. When the input voltage-different high， the output current will also be high， notice that the consumption should not be too high. In the normal condition the consumption dont over 20W. So recommend classification regulator voltage. Package included: 1 x 1.25V-37V AC\/DC to DC LM317 adjustable voltage regulator
