TL430ILP

Overview

The TL430ILP is a three-terminal adjustable shunt regulator manufactured by Texas Instruments, housed in a TO-92-3 through-hole package. It functions as a precision voltage reference with an adjustable output range from 2.75 V to 30 V. The device features an initial accuracy of ±9% and a temperature coefficient of 120 ppm/°C. It supports a maximum shunt current of 100 mA and operates within a temperature range of 0°C to +70°C. The component integrates a bandgap reference core for stable performance.

Feature Summary

• Provides adjustable shunt regulation capability across a wide voltage range
• Integrates a stable bandgap reference core for consistent performance
• Designed for through-hole mounting in standard TO-92 packages

Applications

• General-purpose voltage reference circuits
• Linear power supply feedback loops
• Comparator threshold setting networks

Procurement Notes

Verify the specific suffix 'ILP' against the manufacturer's latest datasheet to confirm the ±9% accuracy grade and commercial temperature range (0°C to +70°C). Ensure the TO-92-3 package matches the target PCB footprint. Cross-reference the part number with official Texas Instruments documentation to distinguish it from higher-precision variants like the TL431 series or other tolerance grades within the TL430 family.

Selection Notes

Select this component when a low-cost, adjustable shunt regulator is required for non-critical voltage referencing applications. The ±9% initial accuracy makes it suitable for general industrial or consumer electronics where tight tolerance is not mandatory. Consider the 100 mA current handling capacity for load requirements and ensure the operating environment stays within the specified commercial temperature limits.

Part Context

The TL430 series serves as a foundational adjustable shunt regulator in Texas Instruments' portfolio, offering a cost-effective alternative to fixed references. It shares functional similarities with the TL431 but typically offers lower precision grades. The ILP designation indicates a specific accuracy bin and package combination within the broader TL430 family, targeting high-volume commercial applications.

Replacement Considerations

Direct replacements include other TL430 variants with compatible pinouts and voltage ranges, such as TL430CLP. For higher precision needs, consider upgrading to the TL431 series, though electrical characteristics and accuracy will differ significantly.
