The typical operating current of the LM4140ACM-1.2/NOPB is around 1.5mA, but it can be as low as 0.5mA or as high as 10mA depending on the application and output current requirements.
To ensure the output voltage of the LM4140ACM-1.2/NOPB remains stable, it's essential to decouple the input and output pins with capacitors, use a low-ESR capacitor for the output capacitor, and minimize noise and interference in the circuit.
While the LM4140ACM-1.2/NOPB can be used as a voltage regulator, it's not recommended as it's primarily designed as a voltage reference. If you need a voltage regulator, consider using a dedicated voltage regulator IC like the LM317 or LM337.
During power-up, the LM4140ACM-1.2/NOPB output voltage may take some time to stabilize. During power-down, the output voltage may droop or oscillate briefly before settling. It's essential to ensure the input voltage is stable and well-regulated to minimize these effects.
The LM4140ACM-1.2/NOPB is rated for operation up to 125°C, but its accuracy and stability may degrade at higher temperatures. If you need a high-temperature voltage reference, consider using a more specialized device designed for high-temperature applications.
