Applications
The TLVH431BCDBVT serves as a precision shunt voltage reference or error amplifier in switching power supply feedback loops where a low 1.24 V reference threshold is required. Its adjustable output spanning 1.24 V to 18 V suits battery charger control circuits, optocoupler-isolated SMPS feedback, and 5-pin SOT-23 footprint constraints on dense analog PCBs. The device is also widely used in industrial and consumer electronics for overvoltage protection and precision biasing applications.

Frequently Asked Questions
What output voltage range does the TLVH431BCDBVT support and how is it adjusted?
The TLVH431BCDBVT supports an adjustable output voltage from 1.24 V up to 18 V, set by an external resistor divider connected to the reference pin. This flexibility lets designers program the exact regulation point for flyback converters, linear regulators, and battery management circuits without switching to a different IC.
How much current can the TLVH431BCDBVT sink in an isolated SMPS feedback application?
The device can sink up to 80 mA of output current, which is sufficient to drive an optocoupler LED directly in most isolated switch-mode power supply feedback topologies. At typical operating points of 5 mA to 20 mA through the LED, the TLVH431BCDBVT provides stable regulation with low temperature drift across a wide operating range.
Why choose the 5-pin SOT-23 package of TLVH431BCDBVT over a larger TO-92 shunt reference?
The 5-pin SOT-23 package occupies approximately 1.6 mm × 2.9 mm of board area, dramatically smaller than a TO-92 through-hole device. For compact IoT sensors, wearables, or multilayer SMD power boards where every square millimeter matters, the SOT-23 format enables tighter component spacing and automated pick-and-place assembly at high volume.
Is TLVH431BCDBVT a suitable lower-voltage alternative to the TL431 in 1.8 V rail monitoring?
Yes. While the classic TL431 requires a minimum 2.5 V reference voltage, the TLVH431BCDBVT's 1.24 V threshold makes it compatible with 1.8 V and 2.5 V supply rails common in modern low-power MCUs and FPGAs. This makes it a direct upgrade for designs migrating from 5 V to sub-2 V logic where TL431 cannot function correctly.
