TL431AQ - three-terminal adjustable shunt regulator

This page provides the datasheet information for the TL431AQ, a member of the TL431 three-terminal adjustable shunt regulator family.

Description

The TL431LI / TL432LI are pin-to-pin alternatives to TL431 / TL432.

TL43xLI offers better stability, lower temperature drift (VI(dev)), and lower reference current (Iref) for improved system accuracy.

Features

  • 1 Reference Voltage Tolerance at 25°C.
  • 0.5% (B Grade).
  • 1% (A Grade).
  • 2% (Standard Grade).
  • Adjustable Output Voltage: Vref to 36 V.
  • Operation From.
  • 40°C to 125°C.
  • Typical Temperature Drift (TL43xB).
  • 6 mV (C Temp).
  • 14 mV (I Temp, Q Temp).
  • Low Output Noise.
  • 0.2-Ω Typical Output Impedance.
  • Sink-Current Capability: 1 mA to 100 mA 2.
