Overview
The TLV431ILPE3 is an adjustable shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range of 2.5V to 36V and provides an adjustable output voltage from 2.495V to 36V. The device supports a maximum cathode current of 100mA with an initial accuracy of 2%. It features a maximum temperature coefficient of 92ppm/°C and functions across a temperature range of -40°C to 85°C. Packaged in a 3-pin TO-92 through-hole configuration, it is designed for automotive applications.
Feature Summary
- Adjustable output voltage capability via external resistor divider
- Automotive-grade qualification for reliable operation
- Low dynamic impedance for stable performance
Applications
- Battery chargers
- Switch mode power supplies
- Battery operated equipment
- Data acquisition systems
Procurement Notes
Verify the exact part number suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure the procurement source provides valid traceability for automotive-grade components. Cross-reference the datasheet revision to confirm compliance with RoHS standards and lead-free specifications required for assembly processes.
Selection Notes
Select this component when an adjustable reference with automotive reliability is required in a through-hole package. Compare the 2% initial accuracy and 92ppm/°C temperature coefficient against application tolerance requirements. Consider the 100mA sink current capability relative to load demands and verify that the TO-92 footprint fits the PCB layout constraints.
Part Context
This component belongs to the TLV431 family of adjustable shunt voltage references. It shares functional similarities with the TL431 but offers enhanced performance characteristics suitable for demanding environments. The TO-92 package distinguishes it from surface-mount variants like the TLV431IDBVR, providing flexibility for legacy or high-power thermal designs.
Replacement Considerations
Public confirmed substitute part numbers include TLV431AIDBVR and TLV431BIDBVR for surface-mount equivalents. Direct pin-to-pin replacements in TO-92 packages should be verified against specific electrical tolerances and automotive qualification status.
