Adjustable power supply (source) with integrated circuit lm350k TO-3 high current
This regulated power supply uses the integrated circuit LM350K (metallic package TO-3) which allows to vary the output tension between 1.2 and 33V with currents of up to 3 Amperes.
The only precaution that she should take, is to set up IC1 in a good heatsink.
T1 – Transformer (110 or 220V) / 24V (or 12+12) / 3A.
IC1 – Integrated Circuit LM350K (ECG970)
D1 – Ponte rectifier KBU4B or similar. Or 4 diodes rectifiers for 5A/100V.
D2 and D3 – Diodes 1N4002 the similar.
C1 – CAPACITOR ELECTROLYTIC 4700µF 50V
C2 – CAPACITOR ELECTROLYTIC 22µF 50V
C3 – CAPACITOR ELECTROLYTIC 100µF 50V
