• $U1: LT1129CS8-3.3\#PBF$ (Low Dropout Regulator)

  • Pins and Connections:

    • GND (Pins 1,2,3): These are ground connections.
    • IN (Pin 4): This is the input voltage pin.
    • OUT (Pin 6): This is the regulated output pin.
    • SENSE (Pin 7): This pin is used to sense the output voltage.
    • SHDN (Pin 8): Shutdown pin to enable/disable the regulator.

• $R4$ (1k Ω Resistor)

  • Pins and Connections:

    • Connects P2 to $C3$:P1 and $R4$:P1 to $R3$:P2, $C2$:P2.

• $C3$ (2.2µF Capacitor)

  • Pins and Connections:

    • Connects P1 to $R4$:P2 and $C3$:P2 to $U1:OUT$. The input voltage is filtered by this capacitor.

• $R3$ (330 Ω Resistor)

  • Pins and Connections:

    • Connects $R3$:P1 to $R2$:P2 and $U1:SENSE$. It is part of the voltage divider.

• $C2$ (10µF Capacitor)

  • Pins and Connections:

    • Connects $C2$:P1 to $U1:SHDN$ and $U1:IN$ and $C2$:P2 to $R3$:P1 and $R2$:P1. This capacitor helps in smoothing the input voltage.

• $R2$ (660 Ω Resistor)

  • Pins and Connections:

    • Connects $R2$:P1 to $U1:OUT$ and $C3$:P2, $R2$:P2 to $R3$:P1 and $U1:SENSE$. Another part of the voltage divider.
