Important notice Dear Customer, On 7 February 2017 the former NXP Standard Product business became a new company with the tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS semiconductors with its focus on the automotive, industrial, computing, consumer and wearable application markets In data sheets and application notes which still contain NXP or Philips Semiconductors references, use the references to Nexperia, as shown below. Instead of TL431 family Adjustable precision shunt regulator Rev. 5 01 September 2015 Product data sheet 1. Product profile 1.1 General description Three-terminal shunt regulator family with an output voltage range between V and 36 V, ref to be set by two external resistors. The TL431xDBZR types feature an enhanced stability area with a very low load capacity requirement. The TL431xFDT types offer an enhanced stability area and a higher ElectroMagnetic Interference (EMI) ruggedness, for example, for Switch Mode Power Supply (SMPS) applications. The TL431xSDT types are designed for standard requirements and linear applications. Table 1.
