Instructions for Using NCV887100D1R2G

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 3.0V to 5.5V.
   • Use appropriate decoupling capacitors (typically 10μF ceramic) close to the input pin to stabilize the input voltage.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 1.2V. No external resistors are required for voltage adjustment.

3. Output Current (IOUT):

   • The device can provide up to 1.5A of continuous output current. Ensure the load does not exceed this limit to avoid overheating or damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 65μA. This is the current consumed by the regulator when no load is applied.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 250mV. Ensure that the input voltage is at least 250mV higher than the output voltage to maintain regulation.

6. Load Regulation:

   • The load regulation is 2mV/A, meaning the output voltage will change by 2mV for every 1A change in load current.

7. Line Regulation:

   • The line regulation is 0.01%/V, indicating that the output voltage will change by 0.01% for every 1V change in input voltage.

8. Power Supply Rejection Ratio (PSRR):

   • At 100kHz, the PSRR is 55dB, which means the regulator can effectively reduce high-frequency noise on the input supply.

9. Operating Junction Temperature (TJ):

   • The operating junction temperature range is from -40°C to 125°C. Ensure proper heat dissipation if the device is expected to operate at high temperatures.

10. Storage Temperature (TSTG):

    • The storage temperature range is from -65°C to 150°C. Store the device in a dry, cool environment to prevent damage.

11. PCB Layout:

    • Place the device and its associated components as close as possible to minimize parasitic inductance and improve performance.
    • Use wide traces for power and ground connections to reduce resistance and improve thermal performance.

12. Capacitors:

    • Use low ESR (Equivalent Series Resistance) capacitors for both input and output to ensure stability and efficiency.
    • For the output, a 10μF ceramic capacitor is recommended to filter out high-frequency noise.

13. Thermal Considerations:

    • If the device is expected to dissipate significant power, consider using a heatsink or a thermal pad to improve heat dissipation.
    • Monitor the temperature of the device during operation to ensure it remains within safe limits.

By following these guidelines, you can ensure optimal performance and reliability of the NCV887100D1R2G in your application.
