Instructions for Using PQ30RV31

1. Input Connection:

   • Connect the positive terminal of the input voltage to the VIN pin.
   • Connect the negative terminal of the input voltage to the GND pin.

2. Output Connection:

   • Connect the VOUT pin to the load or circuit requiring the regulated 3.3V supply.
   • Ensure the load does not exceed the maximum output current of 300mA.

3. Ground Connection:

   • Ensure a solid connection between the GND pin and the ground of the system to maintain stability and performance.

4. Capacitors:

   • Place a 1渭F ceramic capacitor close to the VIN and GND pins to filter input noise.
   • Place a 1渭F ceramic capacitor close to the VOUT and GND pins to stabilize the output.

5. Thermal Management:

   • Ensure adequate heat dissipation, especially when operating near the maximum output current. The device has a typical thermal resistance of 120掳C/W.
   • Use a heatsink if necessary, especially in high ambient temperatures or high power applications.

6. Operating Temperature:

   • The device is designed to operate within the temperature range of -40掳C to 85掳C. Ensure that the ambient temperature does not exceed these limits to avoid damage or reduced performance.

7. Storage:

   • Store the device in a dry environment with temperatures ranging from -65掳C to 150掳C to prevent damage.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.
