Pinout
1. Pin 1 (ADJ/GND): This pin is used for the adjustable output voltage configuration. In fixed voltage versions, this pin is grounded.
2. Pin 2 (VOUT): This is the output pin, which provides the regulated voltage. The output voltage can be fixed or adjustable, depending on the specific version of the component.
3. Pin 3 (VIN): This pin is the input for the unregulated voltage that needs to be regulated down to a stable output voltage.
4. Tab: The exposed tab is usually connected to the output pin (VOUT) and can also be used for heat dissipation.
The LD1117SC-R is commonly used for providing a stable output voltage with a relatively low dropout, making it suitable for applications where efficiency and space are important.
