Linear Power supply Module regulated DC +/- LM317T / LM337 1.25V / 18V 0.5A

This symmetrical regulated DC linear power supply module with dual LM337 negative and LM317 positive regulators is designed to cleanly power any DC circuit from 1.25V to 18V output at 0.5A (LM317 current).

Fitted as standard with a 230V 15 VA moulded transformer mounted on the printed circuit board, installation is simple. It features two screw potentiometers (one per regulator) for voltage adjustment from 1.25 to 18V DC using a simple flathead screwdriver.

Its particularly rigorous design, and the quality of its components, make it an excellent choice for powering any low-voltage high-fidelity element such as certain DAC converters, headphone amplifiers, etc... All of which contribute to improving sound quality.
