NXP voltage references

TL431 and TLVH431 families

Adjustable precision voltage references

for power management and more

As`part`of`NXP’s`proven`portfolio`of`precision`shunt`regulators,`these`adjustable`voltage`

references`are`an`ideal`choice`for`power`management`and`other`applications.`They`use`a`reference`

voltage`of`1.24`V`(TLVH431)`or`2.495`(TL431),`are`housed`in`SOT23`and`SOT753`packages,`and`are`

available`in`several`versions,`so`it’s`easy`to`ﬁnd`the`right`part`for`your`design.`

Key features

Isolated feedback loop for SMPS

``Simple`solution`to`achieve`a`stabilized`voltage

``Enables`regulated`voltage`down`to`1.24`V`(TLVH431)

``V_max`up`to`36`V`(TL431)

``Available`with`voltage`accuracy`down`to`0.5%

``Low`I_kmin`value`of`55`µA`(typ)`for`improved`energy

efﬁciency`(TLVH431)

``Full`temperature`range`from`-40`to`125`°C

``Very`low`temperature`drift:`4`mV`for`TLVH431

``High`quality`level`according`to`AEC-Q100`(grade1)

Key applications

``Power`adaptor

Shunt voltage regulator

``LCD`TV

``Printer

``Computing

``Shunt`regulator`

``Precision`voltage`reference

``Isolated`feedback`loop`for`SMPS
