Pinout
Pin Functions:
1. Input (VIN): This is where the input voltage is applied. The voltage should be higher than the desired output voltage.
2. Ground (GND): The ground reference for the regulator circuit.
3. Output (VOUT): This pin provides the regulated output voltage, which is fixed at 15V for the LM2990T-15.
4. Adjust (ADJ): This pin is used for adjusting the output voltage if needed, though the LM2990T-15 is designed for a fixed output.
5. Bypass (BYP): This pin is connected to a capacitor to improve transient response and noise performance.
The LM2990T-15 is typically used in applications requiring a stable 15V power supply with low dropout voltage.
