In Many electronic projects output actuators or ouput device needs 12 volt regulated power supply like, LCD, Graphic Lcd and DC geared motors. This Circuit brings Regulated 12 Volt DC from bridge rectifier and a IC7812, this circuit uses 100uF capacitor as a simple filter to remove large ac ripples form rectified DC, and the capacitor 0.1uF capacitor removes small size ac ripples from Regulated DC ouput.
Components List
| S.No | Name | Quantity |
| 1. | Diode 1N4001 | 4 |
| 2. | Capacitor 100uF & 0.1uF | each 1 |
| 3. | IC 7812 | 1 |
Note: Step down transformer is not illustrated in this circuit diagram.
Hello,
my step down transformer outputs 15VAC so would i get 12VDC from this circuit or less ?
Kind regards,
NO, your step down transformer outputs 15v Sine wave (AC). Hence by using a full bridge rectifier you can convert it to 15 volts DC
Plzz give me diod,ic and capacitor valive for 12v 400ma tranformer
