Hello electron manipulators. I have a 555 and its wired up in astable mode, so it has a period on and a period off. When i measure the ouptut voltage with no load, it is same as input, but when attatched to a load, it drops a few volts. Since its a switch that repeatedly turns off and on, i dont know what to put at the output, or anywhere, to stabalize the output voltage. I have 12 volts on input and a 12 volt relay coil on the output, so, any ideas how to feed the relay coil with a solid 12 volts, in a simple and inexpensive way, will be greatly appreciated. Thanks
