TL431CDR Description

Short technical summary and product information.

The TL431CDR is a three-terminal adjustable precision shunt regulator manufactured by Texas Instruments. It provides a stable output voltage that can be set between Vref (approximately 2.5V) and 36V using two external resistors. The device offers different reference voltage tolerances depending on the grade, ranging from 0.5% for the B grade to 2% for the standard grade, measured at 25°C.

 

With a typical output impedance of 0.2Ω, the TL431CDR features active output circuitry for a sharp turn-on characteristic, making it a suitable replacement for Zener diodes in applications such as on-board regulation, adjustable power supplies, and switching power supplies. It operates over a temperature range of 0°C to 70°C and has a sink-current capability from 1mA to 100mA.

 

This component is supplied in an 8-pin SOIC package suitable for surface mounting. The standard package quantity is 2,500 units on tape and reel.
