This project can be used to power up TTL and CMOS based projects, it provides 5 VDC & 12 VDC outputs with an onboard mains transformer. The project is based on the industry popular 7800 series voltage regulator in TO220 packages.
Features
- Input: 240 VAC
- Output: 5 V, 12 V @ 600 mA regulated low ripple DC voltage
- Thermal overload/short circuit protection (provided by IC feature)
- Power Battery Terminal (PBT) for easy input and output connection
- External On/Off switch connection possible
- LED indication for outputs
- Four mounting holes of 3.2 mm each
- PCB dimensions 87 mm x 49 mm

nice work
Can u plese make me a 0 to 12 volt power supply
what is j1 OMIT i cant understand
It means not to be used.
Nice work
Regulator ICs without heatsinks? For 600mA itsok but what component will limit the current not to be exceeded?for 7805 … input voltage is already much greater than the output 5volts… the more that difference…IC needs to be heatsinked… how is this circuit tested?
Yes, this board requires a heatsink to deliver the full output power. It’s just not present on the photos.
