Instructions for Use:

1. Circuit Configuration:

   • Connect the reference voltage (Vref) to the reference pin.
   • Connect the load resistor (RL) between the output pin and ground.
   • Ensure the input voltage (Vadj) is within the specified range (0 to 30V).

2. Output Current:

   • The LM234Z-6/NOPB can provide a maximum output current of 6mA.
   • For higher currents, consider using external transistors or other current boosting circuits.

3. Reference Voltage:

   • The reference voltage (Vref) is typically set to 5V.
   • Ensure that the reference voltage is stable and within the specified tolerance (4.995V to 5.005V).

4. Line and Load Regulation:

   • The line regulation is very low (0.001%/V), ensuring minimal changes in output current with variations in input voltage.
   • The load regulation is also low (0.01%/mA), ensuring stable output current over a range of load conditions.

5. Temperature Coefficient:

   • The temperature coefficient is ±10 ppm/°C, which means the reference voltage will change by ±10 parts per million for each degree Celsius change in temperature.

6. Dropout Voltage:

   • The dropout voltage is 0.7V at full load (6mA). Ensure that the input voltage is at least 0.7V higher than the desired output voltage.

7. Operating and Storage Temperatures:

   • The device can operate over a temperature range of -40°C to 125°C.
   • Store the device in an environment with temperatures ranging from -65°C to 150°C.

8. Quiescent Current:

   • The quiescent current is relatively low, ranging from 50μA to 150μA, making the device suitable for low-power applications.

9. Capacitors:

   • Use appropriate bypass capacitors (typically 0.1μF ceramic capacitors) on the input and output pins to filter noise and ensure stability.

10. Handling:

    • Handle the device with care to avoid damage from electrostatic discharge (ESD).
    • Follow proper soldering techniques and avoid excessive heat during assembly.
