TLV431ALPRAG

Overview

The TLV431ALPRAG is a low voltage precision adjustable shunt regulator from the TLV431A series manufactured by onsemi. It features a programmable output voltage range of 1.24 V to 16 V and a guaranteed reference accuracy of ±1.0% at 25 °C. The device operates within an ambient temperature range of -40 °C to 85 °C and supports a cathode current range of 0.1 mA to 20 mA. It utilizes a TO-92-3 package with bent leads and is supplied in tape and reel packaging containing 2000 units.

Feature Summary

Programmable output voltage range spanning 1.24 V to 16 V
Guaranteed reference accuracy of ±1.0% at 25 °C
Sharp low current turn-on characteristic
Low dynamic output impedance

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 the specific ordering suffix ALPRAG corresponds to the required TO-92-3 package with bent leads and tape and reel shipping configuration. Confirm that the A-series accuracy specification meets the design requirements. Ensure the operating environment remains within the specified industrial temperature limits. Check for any obsolete status updates as this component family has undergone discontinuation notices for related variants.

Selection Notes

Select the TLV431ALPRAG when a precise, low-cost shunt regulator is needed for feedback loops or voltage references. The A-series tolerance suits general precision applications where tighter B or C series tolerances are unnecessary. Consider the TO-92-3 through-hole package for prototyping or high-reliability manual assembly. Verify stability boundaries if significant load capacitance is present in the circuit design.

Part Context

This component belongs to the TLV431 family of low voltage precision adjustable shunt regulators produced by onsemi. The family includes A, B, and C series variants offering different accuracy levels. The TLV431A specifically targets applications requiring ±1.0% initial accuracy. These devices serve as direct replacements for Zener diodes in circuits demanding higher precision and lower dynamic impedance.
