Pinout
1. Pin 1 (Input): This pin is connected to the unregulated input voltage. The input voltage must be more negative than the output voltage, typically needing to be at least -17V to -35V to ensure proper regulation.
2. Pin 2 (Ground): This is the common ground pin for both the input and output. It is the reference point for the output voltage.
3. Pin 3 (Output): This pin provides the regulated output voltage of -15V. It supplies a constant voltage as long as the input voltage and load conditions are within the specified range.
The L7915CV can deliver up to 1.5A of output current, depending on the input-output differential voltage and ambient temperature. It is commonly used in power supply circuits requiring stable negative voltage regulation.
