Description

Diodes Incorporated TL431BSA-7 Precision Shunt Regulator

The TL431BSA-7 from Diodes Incorporated is a versatile and precision programmable shunt regulator that is encapsulated in a small SOT-23 package. This three-terminal adjustable regulator can be set to any value between Vref (approximately 2.495 volts) and 36 volts with two external resistors. This device exhibits a low output noise, making it suitable for precision applications.

The TL431BSA-7 offers excellent temperature stability and output current handling capability up to 100mA. Its typical output impedance is 0.2 ohms, a feature that contributes to its stable and reliable performance over a wide range of operating conditions. The device's sharp turn-on characteristics make it an excellent replacement for Zener diodes in many applications, such as adjustable voltage references, switched-mode power supplies, and linear regulators.

Key features of the TL431BSA-7 include:

  • Adjustable Output Voltage: Can be set from Vref to 36V.
  • Low Operational Cathode Current: Ranging from 1mA to 100mA.
  • Low Dynamic Output Impedance: 0.2 ohms typical, ensuring good load regulation.
  • Fast Turn-On Response: Suitable for applications requiring a quick response time.
  • Thermal Stability: High stability over the full operating temperature range.
  • Surface-Mount Package: SOT-23 package allows for efficient use of PCB space and is ideal for automated assembly processes.

Applications for the TL431BSA-7 are diverse and include being used as a precision voltage reference, part of a voltage monitoring circuit in power supplies, or as a current limiter in battery chargers. Its reliability and precision make it a go-to component in the design of consumer electronics, automotive systems, and industrial controls where voltage regulation is critical.

With its combination of features, the TL431BSA-7 from Diodes Incorporated provides designers with a compact, flexible, and reliable solution for voltage regulation needs in a wide array of electronic circuits.
