Pinout
The device comes in a small 6-pin SOT-23 package. Here is a brief overview of its pin functions:
1. Pin 1 (OUT): This is the output pin where the inverted voltage is available.
2. Pin 2 (CAP+ or C1+): Connect a capacitor here to assist in the charge-pump operation.
3. Pin 3 (GND): Ground pin for the device.
4. Pin 4 (CAP- or C1-): Connect this to the other end of the capacitor used in the charge-pump operation.
5. Pin 5 (LV): Low Voltage Pin. Used for logic-level control and enables low-voltage operation.
6. Pin 6 (V+ or VCC): Connects to the positive input voltage that needs to be inverted.
The LM2665 is typically used in applications requiring negative voltage outputs, such as powering analog circuits, or where a negative rail is needed from a positive supply.
