TL431ILPRPG

Overview

The TL431ILPRPG is a three-terminal programmable shunt regulator diode manufactured by onsemi. It operates as a low temperature coefficient zener, providing a reference voltage adjustable from Vref to 36 V using two external resistors. The device features a wide operating current range of 1.0 mA to 100 mA and a typical dynamic impedance of 0.22 Ω. It offers a reference input voltage tolerance of ±2.2% at 25 °C and an equivalent full-range temperature coefficient of 50 ppm/°C. Designed for industrial applications, it supports an ambient temperature range of -40 °C to +85 °C and is housed in a TO-92 (TO-226) package with bent leads.

Feature Summary

Programmable output voltage capability up to 36 V
Low dynamic output impedance for stable regulation
Temperature compensated operation across the rated range
Lead-free and halogen-free construction compliant with RoHS standards

Applications

Digital voltmeters
Power supplies
Op amp circuitry
Voltage monitors

Procurement Notes

Verify the specific suffix 'LP' corresponds to the required TO-92 bent lead configuration. Confirm that the 'I' grade tolerance meets design requirements. Check for active status or obsolescence notices. Ensure compatibility with the target PCB footprint for the specified package style.

Selection Notes

Select this component when a precision shunt regulator is needed within the -40 °C to +85 °C range. The ±2.2% tolerance suits general-purpose applications where tighter accuracy is not critical. Consider thermal dissipation limits if operating near maximum cathode currents. Verify stability boundary conditions for the specific load capacitance in feedback loops.

Part Context

This part belongs to the TL431 family of programmable precision references. It serves as a direct replacement for standard Zener diodes in many circuits. The device integrates internal compensation for temperature variations. It is widely used in power management and signal conditioning designs requiring a stable reference voltage.
