Overview
The IRU431-L3TR is a low-voltage adjustable precision shunt regulator manufactured by Infineon Technologies. It functions as a three-terminal voltage reference device designed for surface-mount applications in the SOT-23-3 package. The component provides an adjustable output voltage range starting from a minimum of 1.24V up to a maximum of 15V. It supports a cathode current of up to 10mA with a tolerance of ±0.97%. The device operates within a temperature range of 0°C to 70°C and requires a minimum cathode current of 80µA for regulation.
Feature Summary
- Adjustable precision shunt regulation capability
- Low-voltage operation design
- Compact surface-mount packaging
Applications
- Voltage reference circuits
- Power supply monitoring
- Battery-operated devices
Procurement Notes
Verify the specific manufacturer designation, as the source data attributes this part to Vishay under document PD94118. Confirm the exact suffix matches the requested model to ensure correct package and tolerance specifications. Cross-reference the datasheet number to validate the electrical parameters against the intended application requirements before procurement.
Selection Notes
Select this component when a low-cost, adjustable voltage reference is required in a small form factor. Ensure the operating environment stays within the specified commercial temperature range. Verify that the load current requirements do not exceed the maximum cathode current rating while maintaining stability above the minimum operating current threshold.
Part Context
This component belongs to the family of low-voltage adjustable precision shunt regulators. These devices are commonly used as reference voltages in analog-to-digital converters and power management systems. The SOT-23-3 package allows for space-constrained designs typical in portable electronics and compact industrial modules.
Replacement Considerations
Check for direct pin-compatible alternatives such as the LM4040 or TL431 series if sourcing from different manufacturers. Ensure the replacement maintains the same adjustable voltage range and tolerance specifications to fit existing circuit layouts without modification.
