Pinout
1. Pin 1 (Input): This is the input pin where the unregulated voltage is supplied. The input voltage must be more negative than -17.5V to ensure proper regulation.
2. Pin 2 (Ground): This pin is connected to the ground of the circuit. It serves as a common reference point for the input and output voltages.
3. Pin 3 (Output): This is the output pin of the regulator, providing a stable -15V output voltage. It can source a current up to 1.5A, provided the input voltage and power dissipation constraints are met.
The L7915ACV is commonly used in power supply circuits to provide a stable negative voltage, often in conjunction with a positive regulator to create a dual-polarity power supply.
