- I developed for my PIC projects but can be used in general-purpose. 9v>5v and 5v>3.3v switch mode regulator
- 3.3v is available in SD card and MMC card project
- No noise with Switch Mode system
- I would particularly recommend , the use of high-speed crystals
- I would recommend the use of tantalum capacitors
- IMPORTANT! – Tantalum capacitors can explode if connected incorrectly
Required Materials
- 1 PCS – 75mmx60mm pertinaks
- 1 PCS – LM2576 IC
- 1 PCS – 79L05 IC
- 1 PCS – LM2576-3.3v IC
- 1 PCS – 1N5819 Diode
- 1 PCS – 100UH Coil
- 2 PCS – 100uf – tantalum Capacitors
- 4 PCS – 1uf – tantalum Capacitors
- 1 PCS – 330uf – electrolytic capacitor
- 2 PCS – 1000uf – electrolytic capacitor
NOTE! – 2pcs 9v battery connected to the circuit input or “ +9v gnd -9v Power Supply” You can use the circuit.
