Breadboard Regulator

This project aims to replicate the work of MB102 breadboard power supply module, by receiving input from DC barrel jack and convert it into 5V and 3.3V output.

Components

• PRT-10811 DC barrel jack
  • Datasheet:
    • Sparkfun
    • Input voltage: 9-12V. Usually, 9V is okay, but depending on the diode used, we may need to use 12V.
• BAT43 Schottky Diode
  • Datasheet:
    • STMicroelectronics
  • In case where Schottky diode is not available, we can use 1N4001 diode.
    • Use 12V input if we use 1N4001 diode to compensate for voltage drop.
• LM7805 IC
  • Datasheet:
    • Sparkfun
    • DatasheetPDF
  • Dependencies:
    • Input capacitor (C-in): 0.33 μF polarized capacitor
    • Input-output noise filtering capacitor(s): 0.1 μF ceramic capacitor
    • Output capacitor (C-out): 0.1 μF polarized capacitor
    • Power indicator: Red LED 5mm
    • Pin header 2.54mm
• LD1117V33 IC
  • Datasheet:
    • Addicore
    • Sparkfun
  • Dependencies:
    • Input-output capacitor (C-in and C-out): 10 μF
    • Input-output noise filtering capacitor(s): 1 μF
    • Power indicator: Red LED 5mm
    • Pin header 2.54mm

Output

- +5V and GND male pins.
- +3.3V and GND male pins.
