TLV431Q

AUTOMOTIVE-COMPLIANT 1.24V SHUNT REGULATOR

Description

Pin Assignments

The TLV431Q is a three-terminal adjustable shunt regulator offering

excellent temperature stability and output current handling capability

up to 20mA. The output voltage may be set to any chosen voltage

between 1.24 and 18 volts by selection of two external divider

resistors.

Notes:

1. The V_REFdeviation is defined as the differences between the maximum and minimum values obtained over the specified temperature range.

2. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.

3. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and

Lead-free.

4. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.

5. Automotive products are AEC-Q100 qualified and are PPAP capable. Refer to https://www.diodes.com/quality/.
