TLV431Q
AUTOMOTIVE GRADE 1.24V SHUNT REGULATOR
Description
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.
The TLV431Q can be used as a replacement for zener diodes in
many applications requiring an improvement in zener performance.
The TLV431Q is available in 3 grades with initial tolerances of 1%,
0.5%, and 0.2% for the A, B and T grades respectively.
The TLV431Q has been qualified to AEC-Q100 Grade 1 and is
Automotive Grade supporting PPAPs

Notes:
1. EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied.
2. See http://www.diodes.com for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
4. Automotive products are AEC-Q10x qualified and are PPAP capable. Automotive, AEC-Q10x and standard products are electrically and thermally
the same, except where specified. For more information, please refer to http://www.diodes.com/quality/product_compliance_definitions/.
