LM317 DC DC LINEAR REGULATOR STEP DOWN POWER MODULE

The LM317 Linear Voltage Regulator Module is a 3-terminal adjustable positive voltage regulator capable of 1.5A output over a 1.2–37V range. Output voltage is set via external resistors. Excellent 0.1% line and load regulation. Full protection suite: current limiting, thermal shutdown, and SOA control. Suitable for low-noise, precision-regulated power supplies where switching noise is unacceptable.
