Mobile charger using 7805ic



This is a typical application circuit of the 7805 IC. We just need two capacitors of vale 33uf and 0.1uf to get this IC working.

The input capacitor 0.33uF is a ceramic capacitor that deals with input inductance problem and the output capacitor 0.1uF is also a ceramic capacitor that adds to the stability of the circuit. These capacitors should be placed close to the terminals for them to work effectively. Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic

CIRCUIT OF MOBILE CHARGER USING 7805IC 






As we all know, the mobile charge input Voltage is 5V, the ic 7805 output Voltage is 5V. So can we use ic 7805 to charge mobile phone

STEP 1: USING IC 7805 TO CONNECT THE CHARGER LINE (connect the charger line with the ic 7805)


STEP 2: TEST THE VOLTAGE (Complete the connecting, connect the circuit, test the input voltage about 8.5V, The output voltage 5V.)

STEP 3: CHARGE TEST (ok tested )
