The LD1117S33TR is a low-dropout linear regulator packaged in a SOT-223 form factor.

Pinout

The LD1117S33TR is a voltage regulator, specifically a low dropout linear regulator. It typically comes in a standard SOT-223 package, which has three pins. Here is a concise description of the pin count and functions:
1. Pin 1 (GND): This is the ground pin, connected to the ground of the circuit. It serves as the reference point for the input and output voltages.
2. Pin 2 (Vout): This pin provides the regulated output voltage. For the LD1117S33TR, the output is fixed at 3.3 volts.
3. Pin 3 (Vin): This pin is used to supply the input voltage to the regulator. The input voltage must be higher than the desired output voltage (3.3V) to ensure proper regulation, typically with a dropout voltage around 1.1V for this model.
The LD1117S33TR is designed for applications requiring a stable 3.3V output with a maximum output current of around 800 mA. It is commonly used in applications involving microcontrollers and other digital circuits requiring a 3.3V power supply.
