Pinout
The pin configuration is as follows:
1. Input (VIN): Connects to the input voltage supply.
2. Ground (GND): Common ground connection.
3. Output (VOUT): Provides the regulated output voltage (1.2V).
4. Enable (EN): Active-high pin to enable or disable the output.
5. Feedback (FB): Used to set the output voltage through feedback.
6. Compensation (COMP): For stability and frequency compensation.
7. Noise Bypass (BP): Optional pin for noise reduction.
8. NC (No Connect): Not internally connected, can be left unconnected.
The LP3992-12B5F is suitable for powering sensitive analog and digital circuits due to its low output noise and high power supply rejection ratio (PSRR).
