The datasheet of ADE7753 specifies that a 5 V +/- 5% (4.75 min / 5.25 max) is needed to power up its digital and analog circuitry. I made a power supply circuit using a 220/9 V Transformer, a bridge rectifier and a 7805 regulator (see attached image). When I tested its output voltage, my multimeter reads 5.4 V. I did not use it to power up the ADE7753, I thought the ADE7753 might get damaged. Instead, I opted to buy a 5 V power supply whose output voltage is 5.25 V when tested with a multimeter. It works fine but I wanted to make my own power supply. Can anyone suggest a circuit schematic that best suits the application of powering up the ADE7753?
All the best,
