Regulated_PSU_G035_1

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

what is j1 OMIT i cant understand

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?
