Overview
The TL431MSDT,215 is a programmable shunt voltage reference manufactured by NXP Semiconductors. It operates within an input voltage range of up to 37 V and provides an output voltage capability of 36 V. The device features an initial accuracy and tolerance of 0.5%. It supports a maximum output current of 100 mA with a supply current of 10 mA. The component is housed in a TO-236-3 (SC-59, SOT-23-3) surface-mount package with three pins. It functions as a single-channel reference and is rated for an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Provides precise adjustable voltage referencing via internal feedback mechanism
- Capable of sourcing high output current for load regulation applications
- Designed for surface-mount installation in compact electronic assemblies
Applications
- Precision voltage references in power supply circuits
- Programmable output regulators
- Temperature compensation circuits
Procurement Notes
Verify the specific suffix '215' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Ensure the ordering part number matches the required tolerance grade and package variant. Confirm RoHS compliance status through the latest datasheet or material declaration provided by NXP Semiconductors prior to procurement.
Selection Notes
Select this component when a low-cost, high-accuracy shunt reference is required for linear regulator feedback loops. The SOT-23-3 package suits space-constrained designs. Verify that the 0.5% tolerance meets system requirements and that the 100 mA output current capability aligns with the intended load conditions.
Part Context
This device belongs to the TL431 family of programmable shunt voltage references. These components are widely used as precision references in switching power supplies and linear regulators. The TL431 series offers a cost-effective alternative to Zener diodes with superior temperature stability and lower dynamic impedance characteristics.
Replacement Considerations
Compatible substitutes include the TL431BSDT,215 and TL431BMFDT,215 from NXP. Other generic equivalents such as the KA431 or LM431 may function similarly but require verification of pinout compatibility and electrical parameter alignment.
