What are the key features of TLV431ACDBVRE4?
- Output voltage adjustable from 1.24V to 6V with a single reference pin, enabling flexible voltage reference design from sub-1.5V rails
- Low reference voltage of 1.24V minimum allows regulation from low-voltage supplies where traditional 2.5V shunt references cannot operate
- SOT-23 5-pin package provides an extremely compact footprint for portable and space-constrained power management circuits
- Precision shunt regulator architecture offers tight output voltage accuracy and low dynamic impedance for stable reference performance
What is TLV431ACDBVRE4 used for?
The TLV431ACDBVRE4 is used as an adjustable precision voltage reference in low-voltage power supply feedback control loops, battery management circuits, and portable electronics where the reference voltage must track supply voltages below 1.5V. It is commonly deployed in switching regulator feedback networks, analog-to-digital converter reference circuits, and precision comparator threshold setting in handheld instruments and IoT sensor nodes. Its adjustable range from 1.24V to 6V makes it a versatile replacement for fixed references across a broad range of power management designs.

Frequently Asked Questions
What is the adjustable output voltage range of the TLV431ACDBVRE4?
The TLV431ACDBVRE4 has an output voltage adjustable from 1.24V to 6V using an external resistor divider connected to the REF pin. This wide adjustment range, starting from a low 1.24V reference voltage, allows it to operate in low-voltage supply systems where conventional 2.5V shunt references like the TL431 are not suitable.
What is the difference between the TLV431 and the standard TL431?
The TLV431 has a lower minimum reference voltage of approximately 1.24V compared to the TL431's 2.5V reference. This makes the TLV431ACDBVRE4 suitable for low-voltage applications powered by 1.8V, 2.5V, or 3.3V rails, where the standard TL431 cannot provide regulation due to its higher reference threshold.
What package does the TLV431ACDBVRE4 use?
The TLV431ACDBVRE4 is housed in a SOT-23 5-pin surface-mount package, designated JESD-30 code R-PDSO-G5. The SOT-23 package offers a very small PCB footprint, making it ideal for compact portable devices, mobile phones, wearables, and IoT sensor boards with limited board space.
Is the TLV431ACDBVRE4 RoHS compliant?
Yes, the TLV431ACDBVRE4 carries a Pbfree code and JESD-609 e4 designation, confirming full RoHS compliance. It is manufactured with a lead-free solder-compatible process meeting current environmental regulations for commercial, industrial, and consumer electronics applications.
What are typical applications for the TLV431ACDBVRE4?
The TLV431ACDBVRE4 is used in switching power supply feedback networks, LDO regulator references, battery charger control circuits, precision voltage comparator threshold setting, and ADC voltage reference applications. Its low minimum reference voltage makes it particularly valuable in 1.8V and 2.5V powered microcontroller and sensor systems.
