TS431IZ Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the TS431IZ is 2.5V to 36V, although it can operate up to 40V with reduced performance.
  • To ensure stability, it's essential to decouple the TS431IZ with a 10nF to 100nF capacitor between the VREF and GND pins, and to keep the output pin (VOUT) as close as possible to the load.
  • The typical output impedance of the TS431IZ is around 0.5 ohms, which means it can drive relatively high currents without significant voltage drop.
  • While the TS431IZ 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, use a dedicated voltage regulator IC for such applications.
  • During power-up, the TS431IZ output voltage (VOUT) follows the input voltage (VIN) until it reaches the internal reference voltage (around 2.5V). During power-down, the output voltage decays slowly due to the internal capacitance.
