TLVH431QDBZT datasheet by Texas Instruments

TLVH431QDBZT Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLVH431QDBZT?
  The recommended operating voltage range for TLVH431QDBZT is 2.7V to 5.5V, although it can operate down to 2.2V with reduced performance.
• How do I ensure stability when using TLVH431QDBZT 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 output capacitor (e.g., 10uF) to filter out noise and ripple.
• What is the typical output impedance of TLVH431QDBZT?
  The typical output impedance of TLVH431QDBZT is around 0.5 ohms, which is relatively low and suitable for most applications.
• Can I use TLVH431QDBZT as a voltage regulator?
  While TLVH431QDBZT can be used as a voltage regulator, it's not recommended due to its limited current sourcing capability (up to 10mA) and lack of short-circuit protection.
• How does TLVH431QDBZT behave during power-up and power-down sequences?
  TLVH431QDBZT has a built-in power-on reset (POR) circuit that ensures a stable output voltage during power-up and power-down sequences, with a typical start-up time of 100us.
