Instructions for Use

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 40V.
   • Do not exceed the maximum input voltage to avoid damaging the device.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted from 1.2V to 36V.
   • Use an external resistor divider to set the desired output voltage.

3. Output Current (IOUT):

   • The device can provide up to 300mA continuously.
   • For higher currents, ensure adequate heat dissipation.

4. Quiescent Current (IQ):

   • The quiescent current is very low at 1.7μA, making it suitable for battery-powered applications.

5. Shutdown Current (ISD):

   • When the shutdown pin (SHDN) is pulled low, the device enters a low-power mode with a shutdown current of 0.1μA.

6. PSRR (Power Supply Rejection Ratio):

   • The device has a high PSRR of 70dB at 100Hz, which helps in filtering out noise from the power supply.

7. Line and Load Regulation:

   • Both line and load regulation are very good, with changes of only 0.01% per volt and per milliamp, respectively.

8. Operating and Storage Temperature:

   • The device can operate over a wide temperature range from -40°C to 125°C.
   • It can be stored at temperatures ranging from -40°C to 150°C.

9. Thermal Considerations:

   • Ensure proper thermal management, especially when operating at high output currents or in high ambient temperatures.

10. Layout Considerations:

    • Place the input and output capacitors as close as possible to the device to minimize parasitic inductance and improve stability.
    • Use a ground plane to help dissipate heat and reduce noise.

11. Capacitor Selection:

    • Use ceramic capacitors with X7R or X5R dielectrics for the input and output capacitors.
    • Typical values are 1μF for the input and 10μF for the output, but these can vary based on specific application requirements.

12. Shutdown Pin (SHDN):

    • Connect the shutdown pin to a logic high (e.g., 5V) to enable the device.
    • Pull the shutdown pin low to disable the device and enter low-power mode.

13. Protection Features:

    • The device includes overcurrent protection and thermal shutdown to prevent damage under fault conditions.

By following these guidelines, you can ensure optimal performance and reliability of the NJW1302G in your application.
