- Battery-operated circuits requiring -5V
- Connect the negative input voltage to the input terminal (IN).
- Connect the output terminal (OUT) to the load or circuit needing the -5V output.
- Ensure the ground terminal (GND) is connected to the system ground.
- Use a heatsink if operating close to the maximum current to manage heat dissipation.
- Ensure input voltage does not exceed the regulator’s maximum rating.
- Proper heat dissipation is necessary to prevent overheating.
- Verify polarity before connecting to avoid damage to the regulator and connected components.
