Instructions for REF02CPZ

1. Input Voltage:

   • Ensure the input voltage is within the specified range of 2.7V to 5.5V to avoid damage or improper operation.

2. Output Voltage:

   • The REF02CPZ provides a fixed output voltage of 2.5V. No external resistors are required for setting the output voltage.

3. Quiescent Current:

   • The quiescent current is typically 60μA at an input voltage of 3V and ambient temperature of 25°C. This value helps in understanding power consumption during operation.

4. Dropout Voltage:

   • The dropout voltage is 1.4V at an output current of 1mA with an input voltage of 3V. Ensure that the difference between input and output voltages is greater than this value for stable operation.

5. Load Regulation:

   • The load regulation is 0.05%, indicating minimal change in output voltage when the load current varies from 0 to 150mA.

6. Line Regulation:

   • The line regulation is 0.01% per volt, meaning the output voltage remains stable even if the input voltage fluctuates.

7. PSRR (Power Supply Rejection Ratio):

   • At 1kHz, the device offers a PSRR of 78dB, effectively rejecting noise from the power supply.

8. Operating Temperature:

   • The operating temperature range is from -40°C to 85°C. Ensure that the device does not exceed these temperatures to prevent thermal stress or failure.

9. Mounting and Handling:

   • Handle the device carefully to avoid static damage. Follow standard ESD precautions.
   • Mount the device on a suitable PCB layout to ensure proper heat dissipation and electrical connections.

10. Capacitor Selection:

    • Choose appropriate input and output capacitors as recommended by the manufacturer to stabilize the output and filter out noise.
