Pinout
1. Input (Vin): This pin receives the input voltage, which should be higher than the output voltage by a specified dropout voltage to regulate the output properly.
2. Output (Vout): This pin provides the regulated output voltage. For the LD1117DT33CTR variant, this is typically fixed at 3.3V.
3. Ground (GND): This pin is the common ground reference for both the input and output, completing the circuit.
The LD1117 series is known for its low dropout voltage, making it suitable for applications where input and output voltages are close to each other. It is commonly used in projects requiring stable voltage regulation with minimal voltage difference between input and output.
