A Product Line of Diodes Incorporated TLV431Q AUTOMOTIVE GRADE 1.24V SHUNT REGULATOR Description Pin Assignments The TLV431Q is a three terminal adjustable shunt regulator offering TLV431 QF (SOT23) excellent temperature stability and output current handling capability up to 20mA. The output voltage may be set to any chosen voltage REF 1 between 1.24 and 18 volts by selection of two external divider 3 ANODE resistors. The TLV431Q can be used as a replacement for zener diodes in CATHODE 2 many applications requiring an improvement in zener performance. (Top View) 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. TLV431 QE5 (SOT25) The TLV431Q has been qualified to AEC-Q100 Grade 1 and is N/C 1 5 ANODE Automotive Grade supporting PPAPs N/C 2 Features CATHODE 3 4 REF Low Voltage Operation V = 1.24V REF Temperature range -40 to +125C (Top View) Reference Voltage Tolerance at +25C 0.2% TLV431TQ 0.5% TLV431BQ Pin should be left floating or connect to anode 1% TLV431AQ Typical temperature drift 4 mV (0C to +70C) Typical Application Circuit 6 mV (-40C to +85C) 11mV (-40C to +125C) 80A Minimum cathode current 0.25 Typical Output Impedance Adjustable Output Voltage V to 18V REF Green Molding Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.

Operation at the absolute maximum ratings, for extended periods, may reduce device reliability. Unless otherwise stated voltages specified are relative to the ANODE pin. These are stress ratings only. Operation outside the absolute maximum ratings may cause device failure. Recommended Operating Conditions ( T = +25C, unless otherwise specified.)
