TLV431BLPRAG

Overview

The TLV431BLPRAG is a discontinued low voltage precision adjustable shunt regulator from onsemi. It belongs to the TLV431B series, featuring a reference accuracy of ±0.5% at 25 °C and ±1.0% over the industrial temperature range of −40 °C to 85 °C. The device operates with a cathode current range of 0.1 mA to 20 mA and supports an output voltage programmable from 1.24 V to 16 V. It utilizes a TO-92-3 package (LP suffix) and is supplied in tape and reel format.

Feature Summary

Precision adjustable shunt regulation with sharp low current turn-on characteristics
Low dynamic output impedance ensuring stable performance across operating currents
Wide operating current range suitable for various power supply applications

Applications

Error amplifier for isolated low output voltage switching power supplies
Adjustable voltage or current linear and switching power supplies
Voltage monitoring circuits
Current source and sink circuits
Low voltage zener diode replacements

Procurement Notes

Verify component status carefully as this specific part number is marked as discontinued in official documentation. Confirm availability through authorized distributors or secondary markets if required for existing designs. Ensure replacement strategies account for the obsolescence status to maintain long-term supply chain stability for production runs.

Selection Notes

Select this component when high precision is required within the −40 °C to 85 °C range. The B-series offers superior initial accuracy compared to the A-series. Consider the TO-92-3 package constraints for through-hole implementations. Evaluate thermal resistance and junction temperature limits under maximum load conditions to ensure reliable operation within specified electrical boundaries.

Part Context

This device is part of the TLV431 family, which includes A, B, and C series variants offering different accuracy levels. The TLV431B specifically targets applications needing tighter tolerance than the standard A-series. It serves as a direct upgrade path for traditional Zener diodes where precise voltage referencing is critical for feedback loop control in power electronics.
