Overview
The TLV431ILPR is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 1.24 V to 6 V and features a maximum cathode current of 15 mA. The device offers high accuracy with initial tolerances of ±0.25%, ±0.5%, or ±1%. It utilizes a TO-92-3 through-hole package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Provides stable reference voltage for low-voltage applications
- Enables precise output regulation via external resistor divider
- Supports wide operating temperature ranges for industrial use
Applications
- Low-voltage power supply regulation
- Portable equipment power management
- Battery-powered system references
Procurement Notes
Verify the specific tolerance grade (A, B, or C) required for your design, as the base part number may correspond to different accuracy levels depending on the suffix. Confirm that the TO-92-3 through-hole package aligns with your PCB layout constraints. Ensure the 15 mA cathode current limit meets the load requirements of your circuit. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.
Selection Notes
Select this component when a low-cost, through-hole adjustable reference is needed for voltages up to 6 V. Compare against the standard TL431 series if higher input voltages up to 36 V are required. Consider the TLV431 family for improved performance in low-voltage scenarios compared to legacy shunt regulators. Evaluate thermal dissipation capabilities within the TO-92 package for your specific power budget.
Part Context
This component belongs to the TLV431 family of low-voltage adjustable shunt regulators. It serves as a modern alternative to the traditional TL431, optimized for lower operating voltages. The family includes various packages and accuracy grades to support diverse power management needs in consumer and industrial electronics.
Replacement Considerations
TLV431ILP is the non-suffix equivalent in bulk packaging. TLV431BCLPR offers 0.5% accuracy. Standard TL431 variants require higher operating voltages.
