Frequently Asked Questions
What output voltage range does the TLVH432IDBZRG4 support, and how is it set?
The TLVH432IDBZRG4 supports an adjustable output voltage from 1.24 V to 18 V, set by an external resistor divider connected to the reference pin. The internal reference voltage is 1.24 V, and the cathode current can reach up to 80 mA, allowing flexible precision reference designs across a wide voltage span.
In which precision analog applications does the TLVH432IDBZRG4 perform best?
This shunt regulator excels in precision voltage reference circuits, op-amp supply rails, and analog-to-digital converter reference inputs where tight voltage accuracy below 1% is required. Its 1.24 V reference and adjustable range up to 18 V make it suitable for sensor conditioning modules, portable test equipment, and low-dropout regulator feedback networks.
How does the SOT-23 package of the TLVH432IDBZRG4 benefit compact board designs?
The 3-pin SOT-23 package occupies a PCB footprint of approximately 1.6 mm x 1.6 mm, making it ideal for high-density boards in wearables, IoT sensor nodes, and handheld instruments. The small outline reduces parasitic inductance and capacitance, which is beneficial for stable shunt reference performance at frequencies up to several MHz.
When should a designer choose TLVH432IDBZRG4 over a fixed-voltage reference like TL431?
The TLVH432IDBZRG4 is preferred when the design requires a reference voltage below the 2.5 V minimum of the standard TL431, since its 1.24 V reference supports low-supply rails common in modern 1.8 V and 3.3 V systems. It also occupies a smaller SOT-23 footprint compared to TL431's SOT-23 variant, with equivalent accuracy for battery-powered and portable designs operating down to 1.24 V.
