Descriptive summary

NXP has the latest standard linear portfolio

NXP’s portfolio of standard linear devices includes precision shunt-, and linear low drop-out voltage regulators. It is part of the TL431 three-terminal shunt regulator family with an output voltage range between Vref = 2.5 V and 36 V, is to be set by two external resistors. NXP’s portfolio extension in 2011 includes TLVH431, shunt regulator in SOT23 with Vin = 20 V max and VREF = 1.24 V. Voltage regulators in SOT223: NX1117 with max output current of 1 A, adjustable from 1.25 V up to 18 V and several fixed output voltage versions 1.2 - 12 V as well as the new automotive LDO NXV426x series.
