The TL431IPK3 is a three-terminal adjustable precision shunt regulator manufactured by Texas Instruments. It is designed for stable thermal performance across various temperature ranges. The output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors.
Key electrical characteristics include a reference voltage tolerance of 0.5% (B grade) at 25°C, a typical output impedance of 0.2Ω, and a sink current capability ranging from 1mA to 100mA. The device operates from -40°C to 85°C.
This shunt regulator is suitable for applications such as on-board regulation, adjustable power supplies, and switching power supplies. Its active output circuitry provides a sharp turn-on characteristic, making it a good replacement for Zener diodes in many designs.
The TL431IPK3 comes in a SOT-89 package suitable for surface mounting. It is supplied in a tape and reel format with a standard package quantity of 1,000 units.
