Variable power supply LM317 from 1.25V to 32V max current 1.5A with heatsink

Variable power supply with adjustable output from 1.25V to 32V. Thanks to the high capacity filter capacitor (4700uF 35V) and the LM317 linear regulator it is possible to have a stable output voltage in any load condition. The maximum input voltage is 35V and in any case it should always be 3V more than what you want to get at the output. So to have 12V at the output you need 12V + 3V = 15V or the input voltage must be between 15V and 35V DC to get the 12V stable at the output. It can deliver up to 1.5A thanks to the included dissipation fin. The circuit is provided with thermal protection in case of over-temperature, protection against polarity inversion, protection against short circuit with current limitation.

Ideal for audio and video fields or signals that are easily sensitive to disturbances, the device does not introduce ripple.
