Pinout
1. Pin 1 (Input): This pin receives the unregulated input voltage, which must be more negative than the desired output voltage. The input voltage should be at least 2V more negative than the output voltage to ensure proper functioning of the regulator.
2. Pin 2 (Ground): This pin is connected to the ground of the circuit. It serves as a reference point for both the input and output voltages.
3. Pin 3 (Output): This pin provides the regulated output voltage of -5V. The output can supply a current of up to 1.5A, assuming the device is appropriately heat-sinked.
The L7905CV-DG features built-in protection against over-current and over-temperature, making it a reliable choice for delivering a stable negative power supply in electronic circuits.
