Datasheet

Adjustable Shunt Voltage Reference IC for Cost-Effective Regulation and SMPS Feedback

The TL431CDBVR is a three-terminal adjustable shunt voltage reference IC designed for general-purpose voltage regulation where cost efficiency and reliability are essential. The output voltage can be programmed from approximately 2.5V up to 36V using two external resistors, making it a flexible replacement for conventional Zener diodes in a wide range of analogue and power management circuits.

With a typical output impedance of 0.2ohm and a sharp turn-on characteristic, the TL431CDBVR delivers stable and predictable regulation behaviour, especially in switch-mode power supply (SMPS) feedback loops, on-board regulation, and adjustable power supplies. The C-grade accuracy makes it suitable for commercial applications where ultra-tight tolerance is not mandatory. Supplied in a compact SOT-23-5 (DBV) package, it integrates easily into space-constrained PCB designs.

Key Features

  • Adjustable output voltage: Programmable from 2.5V to 36V
  • Standard C-grade accuracy: +-2% initial tolerance at 25 C
  • Low output impedance: Typically 0.2ohm for stable regulation
  • High sink current capability: Supports up to 100mA cathode current
  • Sharp turn-on characteristic: Suitable for threshold detection and feedback control
  • Zener diode replacement: Improved performance over discrete Zeners
  • Compact SMD package: SOT-23-5 for dense PCB layouts
  • RoHS compliant: Lead-free device
