Instructions for REF02CJ

1. Input Voltage Connection:

   • Ensure the input voltage is within the operating range of 2.7V to 5.5V.

2. Output Voltage:

   • The REF02CJ provides a fixed output voltage of 2.5V. No external resistors are required for setting the output voltage.

3. Quiescent Current:

   • The device has a quiescent current of approximately 10μA at an input voltage of 5V with no load. This low quiescent current helps in minimizing power consumption.

4. Dropout Voltage:

   • For optimal performance, ensure that the difference between the input and output voltages is greater than the dropout voltage, which is typically 200mV at an output current of 100μA.

5. Load Regulation:

   • The device maintains a stable output voltage with changes in load current from 100μA to 10mA, with a typical variation of 5mV.

6. Line Regulation:

   • The output voltage remains stable over the input voltage range from 2.7V to 5.5V, with a typical variation of 5mV.

7. Power Supply Rejection Ratio (PSRR):

   • The REF02CJ offers good rejection of ripple on the input supply, providing a PSRR of 80dB at 1kHz.

8. Application Considerations:

   • Use appropriate bypass capacitors on both the input and output to minimize noise and improve stability.
   • Ensure proper PCB layout practices to avoid potential issues with electromagnetic interference (EMI).

These parameters and instructions are essential for the correct application and operation of the REF02CJ reference voltage regulator.
