Instructions for LM231N:

1. Supply Voltage Connection: Connect the supply voltage between the Vcc and GND pins. Ensure the voltage is within the operating range of 7V to 40V.
2. Output Configuration: The output voltage can be adjusted by using external resistors connected to the adjust pin. The typical reference voltage is 1.23V.
3. Line and Load Regulation: The device maintains a stable output voltage with changes in input voltage and load current, as specified by line and load regulation parameters.
4. Temperature Considerations: Be aware of the temperature coefficient which affects the reference voltage stability over temperature changes.
5. Current Limitation: The maximum continuous output current should not exceed 10mA.
6. Quiescent Current: The quiescent current is very low, typically around 60μA, which helps in reducing power consumption.
7. Noise Rejection: The device provides good power supply rejection ratio at 1kHz, ensuring minimal noise in the output voltage.
8. Capacitor Selection: Use appropriate capacitors on the output to ensure stability, especially if the load has high capacitance or reactance.
