TL431BCLPRMG

Overview

The TL431BCLPRMG is a three-terminal programmable shunt regulator IC from onsemi, housed in a TO-92 (TO-226) package. It operates as a low temperature coefficient zener diode with an adjustable output voltage range from the internal reference up to 36 V. The device features a typical voltage reference tolerance of ±0.4% at 25 °C and supports a cathode current range of 1.0 mA to 100 mA. It exhibits a typical dynamic impedance of 0.22 Ω and an equivalent full-range temperature coefficient of 50 ppm/°C.

Feature Summary

Programmable precision reference utilizing two external resistors for voltage setting
High accuracy with ±0.4% initial tolerance at room temperature
Low dynamic output impedance for stable regulation performance
Temperature compensated operation across the rated ambient range

Applications

Feedback control loops driving optocouplers in power supplies
Digital voltmeter reference circuits
Op amp circuitry requiring stable biasing
Constant current sources and sinks
Voltage monitor applications

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and Pb-free status against current manufacturing standards. Check datasheet revision history for any updates to electrical characteristics or marking codes. Ensure the TO-92 package style matches the specific pinout requirements of the target design.

Selection Notes

Select this variant when high initial accuracy is required compared to standard tolerance versions. Verify that the operating temperature range meets the application's environmental constraints. Consider the thermal resistance characteristics of the TO-92 package for power dissipation calculations. Ensure the cathode current limits align with the circuit's load requirements.

Part Context

This component belongs to the TL431 family of programmable shunt regulators manufactured by onsemi. It serves as a direct replacement for traditional Zener diodes in precision applications. The B suffix indicates the tighter voltage tolerance grade within the series. The LP suffix denotes the specific TO-92 plastic package configuration used for through-hole mounting.
