LMV431ACM5X datasheet by Texas Instruments

LMV431ACM5X Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for LMV431ACM5X?
  The recommended operating voltage range for LMV431ACM5X is 1.6V to 5.5V. However, it can operate up to 15V with reduced accuracy and stability.
• How do I ensure stability when using LMV431ACM5X as a voltage reference?
  To ensure stability, it's recommended to decouple the input pin with a 10nF to 100nF capacitor, and use a low-ESR capacitor (e.g., ceramic or film capacitor) for the output capacitor. Additionally, keep the layout clean and avoid noise coupling.
• What is the typical output impedance of LMV431ACM5X?
  The typical output impedance of LMV431ACM5X is around 0.5 ohms. This is relatively low, making it suitable for applications where a low-impedance voltage reference is required.
• Can I use LMV431ACM5X as a voltage regulator?
  While LMV431ACM5X can be used as a voltage regulator, it's not recommended due to its limited current capability (up to 10mA) and lack of short-circuit protection. Instead, consider using a dedicated voltage regulator IC.
• How does temperature affect the accuracy of LMV431ACM5X?
  The accuracy of LMV431ACM5X is affected by temperature, with a typical temperature coefficient of -0.5mV/°C. This means that the output voltage will decrease by 0.5mV for every 1°C increase in temperature.
