Instructions for Use:
Power Supply:
- Ensure the input voltage (VI) is within the specified range of 2.7 V to 5.5 V.
- The input voltage should be stable and free from excessive noise to maintain accurate output regulation.
Output Voltage:
- The REF02AU provides a fixed output voltage of 1.24 V. This voltage is suitable for precision reference applications.
- The output voltage is stable over a wide range of load currents and temperatures.
Line Regulation:
- The line regulation is very low at 0.002% per volt, ensuring minimal output voltage variation with changes in input voltage.
Load Regulation:
- The load regulation is also very low at 0.002% per milliamp, ensuring minimal output voltage variation with changes in load current.
Temperature Coefficient:
- The temperature coefficient is 10 ppm/°C, indicating that the output voltage will change by 10 parts per million for each degree Celsius change in temperature.
Dropout Voltage:
- The dropout voltage is 1.5 V at a load current of 10 mA. Ensure that the input voltage is at least 1.5 V higher than the output voltage to maintain regulation.
Quiescent Current:
- The quiescent current is 60 μA at an input voltage of 5 V with no load. This low quiescent current makes the REF02AU suitable for battery-powered applications.
Output Current:
- The REF02AU can provide a continuous output current of up to 10 mA. Ensure that the load does not exceed this limit to avoid damage or reduced performance.
Operating Temperature:
- The device is designed to operate over a temperature range of -40°C to +85°C. Ensure that the ambient temperature stays within this range for optimal performance.
Storage Temperature:
- The device can be stored at temperatures ranging from -65°C to +150°C. However, ensure that it is brought to operating temperature before use to avoid thermal shock.
Handling and Installation:
- Handle the REF02AU with care to avoid static discharge and physical damage.
- Follow standard soldering practices to ensure reliable connections and prevent thermal stress on the device.
Application Notes:
- For best performance, use bypass capacitors (typically 0.1 μF and 10 μF) close to the input and output pins to filter out noise and stabilize the voltage.
- Refer to the datasheet for detailed application circuits and additional information.
