Pinout
- Pin Count: 3 pins
- Function: It is designed to provide a negative output voltage from a higher negative input voltage. The output voltage is adjustable and can range from -1.2V to -37V, depending on the resistor configuration.
Pin Functions:
1. Input (IN): This pin receives the negative input voltage.
2. Output (OUT): The regulated negative output voltage is provided on this pin.
3. Adjust (ADJ): This pin is used to adjust the output voltage. By connecting resistors between the Output and Adjust pins, and from the Adjust pin to ground, the output voltage can be set according to the desired level.
This component is commonly used in applications requiring negative voltage regulation with good load and line regulation characteristics.
