TL430CLPR

Overview

The TL430CLPR is a three-terminal adjustable shunt regulator from Texas Instruments, housed in a TO-92 (LP) package. It features an internal reference voltage of 2.75 V typical and supports an operating temperature range of 0°C to 70°C. The device regulates cathode currents between 2 mA and 100 mA with a maximum regulator voltage of 30 V. Output voltage is programmable via two external resistors within the 3 V to 30 V range.

Feature Summary

• Temperature compensated for stable operation across specified ranges
• Programmable output voltage set by external resistors
• Low output resistance for effective regulation
• Low output noise characteristics

Applications

• Replacing Zener diodes for improved performance
• Shunt regulator circuits
• Series regulator configurations
• Current limiter designs
• VCC monitor applications

Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the tape and reel packaging format containing 2000 units per reel. Confirm that the TL430C variant meets the required thermal environment constraints, as it is characterized strictly for operation between 0°C and 70°C ambient temperatures. Ensure component selection aligns with the absolute maximum ratings provided in the datasheet.

Selection Notes

Select this component when a low-cost, adjustable precision shunt regulator is needed to replace standard Zener diodes. The TL430CLPR is suitable for applications requiring sink capability up to 100 mA and precise voltage setting between 3 V and 30 V. Consider the TO-92 through-hole package for prototyping or lower-volume production environments where surface mount options are not mandatory.

Part Context

The TL430 series serves as a fundamental adjustable shunt regulator within Texas Instruments' power management portfolio. It provides a cost-effective alternative to discrete Zener diodes while offering superior stability and noise performance. The device integrates a temperature-compensated bandgap reference to maintain accuracy across its operational range.

Replacement Considerations

Direct replacements include the TL430CLP for bulk packaging requirements.
