Key Features
- Adjustable output voltage from 1.24V to 18V using two external resistors for flexible reference and regulation needs
- Low minimum reference voltage of 1.24V enables shunt regulation in 1.8V and 3.3V low-voltage supply rails
- Up to 80mA output current supports direct driving of small loads and feedback networks in power supplies
- 5-pin SOT-23 package (R-PDSO-G5) minimizes PCB footprint in space-constrained portable and IoT applications
Applications
The TLVH431CDBVTG4 is used as a precision voltage reference and shunt regulator in switching power supplies, battery chargers, and linear regulators requiring low-voltage feedback control. Its adjustable output and low knee voltage make it ideal for 3.3V and 1.8V power management circuits in IoT modules, wearables, and handheld instruments. It is also commonly used in over-voltage protection and error amplifier circuits in isolated flyback and buck converter designs.

Frequently Asked Questions
What output voltage range does the TLVH431CDBVTG4 support?
The TLVH431CDBVTG4 supports an adjustable output voltage from 1.24V to 18V, set by two external resistors. The 1.24V minimum reference voltage allows it to regulate low-voltage rails as low as 1.24V, which is lower than the standard TL431's 2.5V minimum.
What is the maximum output current of the TLVH431CDBVTG4?
The TLVH431CDBVTG4 can sink up to 80mA of output current, making it capable of directly driving small loads, optocoupler LEDs in isolated power supplies, and feedback networks in switching regulator control loops.
What package does the TLVH431CDBVTG4 use and is it RoHS compliant?
The TLVH431CDBVTG4 is housed in a 5-pin SOT-23 surface-mount package (JESD-30 R-PDSO-G5) and carries JESD-609 code e4, confirming it is lead-free and fully RoHS compliant for consumer, industrial, and regulated electronic applications worldwide.
How does the TLVH431CDBVTG4 differ from a standard TL431?
Unlike the standard TL431 which requires a minimum reference voltage of 2.5V, the TLVH431CDBVTG4 operates with a 1.24V minimum output voltage, enabling shunt regulation in low-voltage power supply designs running from 3.3V or lower supply rails common in modern microcontroller and IoT systems.
