LM317 Mini Power Amplifier Circuit

You probably know with the purpose of LM317 IC is used being an changeable voltage manager, but did you know it can take place used as an audio amplifier? This is a taste A audio amplifier built with LM317 so as to delivers a utmost 1W audio power.

LM317 Mini Power Amplifier Circuit

Manipulate a worthy heatsink pro the LM317 IC and adjust the 5K inconsistent resistor so with the aim of you allow 4.5V on 10Ω resistor (otherwise LM317 pin 2, Vout).

Component List :
R1 = 2k2 Ohm
R2 = 10 Ohm 2Watt
VR = 5k Ohm
C1 = 10uF / 16V
C2 = 470uF / 50V
Voltage Source = 9V - 14.7V DC

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.
