Overview
The TLV431BCDBZTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 1.24 V to 6 V and supports a maximum output current of 15 mA. The device features an initial accuracy of 0.5% and a maximum temperature coefficient of 138 ppm/°C. It functions with a maximum input voltage of 7 V and operates across a temperature range from -40 °C to 85 °C. The component is housed in a surface-mount SOT-23 package with three pins and is supplied in tape and reel packaging.
Feature Summary
- Provides adjustable reference voltage functionality using a shunt topology for precise regulation.
- Delivers high initial accuracy suitable for applications requiring tight voltage tolerance.
- Designed for low-voltage operation with extended industrial temperature stability.
Applications
- Precision voltage references in portable electronic devices
- Feedback control loops in switching power supplies
- Battery-powered equipment requiring stable reference voltages
Procurement Notes
Verify the specific suffix 'TG4' confirms RoHS compliance and lead-free status as per manufacturer documentation. Ensure the order specifies the tape and reel packaging format, distinct from tube or cut tape options. Confirm the automotive or industrial grade designation matches the required environmental operating conditions for the target application design.
Selection Notes
Select this component when a low-voltage adjustable reference with 0.5% accuracy is required. It is appropriate for designs where space is limited due to the compact SOT-23 footprint. Consider the 15 mA current limit when determining load requirements. Verify that the 7 V maximum input voltage aligns with the system supply rails.
Part Context
This part belongs to the TLV431 family of low-voltage adjustable precision shunt regulators. It serves as a modern alternative to traditional Zener diodes, offering superior accuracy and lower temperature drift. The device integrates a bandgap reference and error amplifier to maintain stable output voltage across varying load and temperature conditions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official manufacturer documentation for recommended replacements or cross-reference guides.
