TL431CLPRP

Overview

The onsemi TL431CLPRP is a three-terminal programmable shunt regulator diode in the TO-92 (TO-226) LP package. It operates as a low temperature coefficient zener, programmable from Vref to 36 V using two external resistors. The device supports a cathode current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω. It features a reference input voltage tolerance of ±2.2% and an equivalent full-range temperature coefficient of 50 ppm/°C. Operating ambient temperature ranges from 0°C to +70°C.

Feature Summary

Programmable output voltage capability up to 36 V via external resistors
Temperature compensated operation across the rated ambient temperature range
Low dynamic output impedance for stable regulation performance
Wide sink current capability supporting 1.0 mA to 100 mA operation

Applications

Digital voltmeters
Power supplies
Op amp circuitry
Shunt regulators
Constant current sources

Procurement Notes

Verify the specific suffix CLPRP corresponds to the TO-92 package with tape and ammo box shipping configuration. Confirm the operating temperature range matches the 0°C to +70°C specification for the C grade. Ensure the ordering code aligns with the required tolerance level and lead form for the intended assembly process.

Selection Notes

Select this component when a precision programmable reference is needed within the commercial temperature range. The TO-92 package suits applications requiring through-hole mounting or specific thermal dissipation characteristics. Consider the 2.2% initial accuracy and 50 ppm/°C temperature coefficient for stability requirements in feedback loops or reference circuits.

Part Context

This part belongs to the TL431, A, B series of programmable precision references manufactured by onsemi. It serves as a monolithic IC voltage reference replacing traditional zener diodes in various analog and power management applications. The family includes variants with different tolerances, packages, and extended temperature ratings such as the NCV prefix for automotive use.
