Overview

The TL431-Q1 is a three-pin adjustable shunt regulator with specified thermal stability over applicable automotive temperature ranges. The output voltage can be set to any value from VREF (approximately 2.5 V) to 36 V, with two external resistors. This device has a typical output impedance of 0.2 Ω. Active output circuitry provides a sharp turnon characteristic, making this device an excellent replacement for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.

Applications

  • Adjustable Voltage and Current Referencing
  • Secondary Side Regulation in Flyback SMPSs
  • Zener Replacement
  • Voltage Monitoring
  • Comparator With Integrated Reference

Key features

  • Qualified for Automotive Applications
  • AEC-Q100 Test Guidance With the Following: Device Temperature Grade 1: -40°C to 125°C Ambient Operating Temperature Range
  • Reference Voltage Tolerance at 25°C: – 1% (A Grade) – 0.5% (B Grade)
  • Typical Temperature Drift: – 14 mV (Q Temp)
  • Low Output Noise
  • 0.2–Ω Typical Output Impedance
  • Sink-Current Capability: 1 mA to 100 mA
  • Adjustable Output Voltage: VREF to 36 V
