Package

The LM1117MP-ADJ is typically available in a SOT-223 package type. This package is a surface-mount design, known for its compact size, suitable for applications where board space is limited.

Pinout

The LM1117MP-ADJ is a low-dropout linear voltage regulator with an adjustable output. It typically comes in a SOT-223 package and features three pins:
1. Input (IN): This is the pin where the unregulated input voltage is applied. It requires an input higher than the desired output voltage by the dropout voltage to function properly.
2. Output (OUT): This pin provides the regulated voltage output. The output voltage is adjustable and determined by the resistor network connected between the output, adjust, and ground.
3. Adjust (ADJ): This pin is used to set the output voltage. A resistor divider network connected to the ADJ pin allows adjustment of the output voltage from a fixed reference voltage.
The LM1117MP-ADJ can provide an output current up to 800 mA and requires external resistors for setting the output voltage. It is suitable for applications requiring efficient, low-dropout voltage regulation.
