LM317 Adjustable Voltage Regulator Module

With Rising-Clamp Terminal Blocks

The LM317 module consists of an adjustable three-terminal positive-voltage regulator. The regulator can supply more than 1.5 A over an output-voltage range from 1.25 V to 37 V.

The module features easy-to-use rising-clamp terminal blocks for connection into your circuit.

Specifications:

• Input and output voltage difference (VI-VO): 40Vdc (maximum value)
• Output adjustable voltage range: 1.2 ～ 37V
• Operating temperature: -55 ° C to + 150 ° C
• Current output: 1.5A maximum
• Voltage input: 4.2 ~ 40 V
• Working temperature: 0 ° C ~ 125 ° C
• Module size: 35mm wide x 17mm deep x 20mm tall
• Input: VIN input positive level, GND input negative
• Output: VOUT output positive stage, GND output negative

Note: This is a linear regulator module, and efficiency will not be very high. To improve efficiency, it is best to have a voltage difference of 3V between the input and output. ≤30V. The input voltage needs to be more than 3V higher than the output voltage to ensure the stability of the output voltage.

Tip: When adjusting the output voltage, adjust the trim pot to desired voltage with no load connected.
