IC 7805 POWER SUPPLY CIRCUIT DIAGRAM
Brief explanation
- The above circuit diagram consists of transformer and electronic components such as diodes,capacitors and 7805IC (regulator I.C).
- Supply is taken from the AC plug and fed to the transformer primary winding through the fuse F1 rting of 2A.
- Secondary of the transformer is given to the bridge rectifier two corners and other two corners connected across capacitor for eliminating the ripples in the wave form
- For accurate supply voltage we have to use the IC 7805 for constant voltge of 5 volts.
Advantages
a) Using 7805 ic accurate voltage obtained.
b) Bridge rectifier helps to increase the reliability of supply.
c) Low distortion due to effective filtering circuit.
d) compact in size durable.
Components
1. I.C 7805.
2. diodes IN4007.
3. transformer 230/9volts.
4. switch 250v,5amp.
5. plug.
6. Capacitors = 3300micro frad, 100 micro farad.
