Overview
The TL431BCDBVT is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495V to 36V and supports a maximum cathode current of 100mA with a minimum operating current of 600µA. The device features an initial accuracy of ±0.5% and a maximum temperature coefficient of 92ppm/°C. It is housed in a surface-mount SOT-23-5 package, measuring 2.9mm x 1.6mm x 1.15mm. The component functions reliably across an ambient temperature range of 0°C to 70°C.
Feature Summary
- Provides stable reference voltage through adjustable shunt regulation topology
- Ensures high precision with ±0.5% initial accuracy specification
- Supports low standby current consumption with 600µA minimum cathode current requirement
Applications
- Precision power supply feedback loops
- Portable equipment voltage references
- Battery-powered system monitoring
Procurement Notes
Verify the specific suffix DBVT confirms the SOT-23-5 package and tape-and-reel delivery format. Confirm the BC grade designation matches the required ±0.5% accuracy for your design. Ensure the 0°C to 70°C operating temperature range aligns with your environmental constraints. Check RoHS compliance status against regional regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact surface-mount solution is required for precise voltage referencing. The SOT-23-5 package offers space efficiency compared to larger alternatives. The 0.5% accuracy suits applications demanding tighter tolerance than standard 1% variants. Consider the thermal performance limits if operating near the upper temperature boundary.
Part Context
This part belongs to the TL431 family of programmable zener diodes widely used in power management. It serves as a cost-effective alternative to fixed voltage references in linear regulators and switching converters. The device integrates a bandgap reference and error amplifier to maintain stable output voltages.
Replacement Considerations
Compatible substitutes include TL431ACDBVT for 1% accuracy or TL431BQDBZRG4 for automotive-grade extended temperature ranges. Verify pinout compatibility and electrical specifications before substitution.
