Description

Circuit schematic like in Figure 1 above is Circuit Schematic Mobile Phone Battery Charger using LM317 IC. Electronichub site describe that as per your need you can take the output from  the circuit by just  flipping the different number of switches (from S3, S4 and S5) in the circuit. If you require the variable power supply as your output than set switch S3 into “on” state. LM317 is used in the circuit which is a variable voltage regulator to  supply variable power. The LM317 is basically positive voltage regulator has three terminals. 1.2 V to  37V is the range of the output  voltage that is provided by the LM317. Different range of voltage can be achieved by just  adjusting  the variable resistor that is provided in the circuit and with the help of multimeter output can be seen and the voltage which is desirable can set. The power supply range  can altar from 1.5V to  12V.
