Overview

Product Highlight

  • Accuracy: ±1 %
  • Reference Voltage: 1.24 V
  • Operating Temp Range: -40 to +85 °C

The TLV431A and B series are precision low voltage shunt regulators that are programmable over a wide voltage range of 1.24 V to 16 V.

The TLV431A series features a guaranteed reference accuracy of ±1.0% at 25°C and ±2.0% over the entire industrial temperature range of −40°C to 85°C. For TLV431B series, the accuracy is even higher, it’s ±0.5% and ±1.0% respectively. These devices exhibit a sharp low current turn−on characteristic with a low dynamic impedance of 0.20 Ω over an operating current range of 100 µA to 20 mA. This combination of features makes this series an excellent replacement for zener diodes in numerous applications circuits that require a precise reference voltage. When combined withan optocoupler, the TLV431A/B can be used as an error amplifier for controlling the feedback loop in isolated low output voltage (3.0 V to 3.3 V) switching power supplies. These devices are available in economical TO−92−3 and micro size TSOP−5 and SOT−23−3 packages.

Key Features:

  • Programmable Output Voltage Range of 1.24 V to 16 V
  • Voltage Reference Tolerance ±1.0% for A Series and ±0.5% for B Series
  • Sharp Low Current Turn−On Characteristic
  • Low Dynamic Output Impedance of 0.20 Ω from 100 µA to 20 mA
  • Wide Operating Current Range of 50 µA to 20 mA
  • Micro Miniature TSOP−5, SOT−23−3 and TO−92−3 Packages
  • Pb−Free Packages are Available

Applications:

  • Low Output Voltage (3.0 V to 3.3 V) Switching Power Supply Error Amplifier
  • Adjustable Voltage or Current Linear and Switching Power Supplies
  • Voltage Monitoring
  • Current Source and Sink Circuits
  • Analog and Digital Circuits Requiring Precision References
  • Low Voltage Zener Diode Replacements
