TL431BQLPME3

Overview

The TL431BQLPME3 is an adjustable precision shunt regulator manufactured by Texas Instruments, designed for high-accuracy voltage reference applications. It operates within a supply voltage range of 2.5 V to 36 V and provides an initial accuracy of 0.5%. The device supports a maximum shunt current of 100 mA with a minimum operating current of 600 µA. It features a temperature coefficient of 92 PPM/°C and functions reliably across an extended temperature range from -40°C to +125°C. Housed in a TO-92-3 through-hole package, this component belongs to the TL431B series and is classified under PMIC voltage references.

Feature Summary

Provides adjustable output voltage capability via external resistor dividers
Ensures stable performance with low temperature coefficient characteristics
Supports wide operating current range suitable for diverse load conditions

Applications

Precision voltage regulation circuits
Power supply feedback loops
Battery-operated equipment monitoring

Procurement Notes

Verify end-of-life status as the manufacturer indicates this component is transitioning to obsolescence. Confirm specific ordering suffixes match required packaging formats such as ammo packs. Ensure compatibility with existing PCB footprints for TO-92-3 packages during design updates.

Selection Notes

Select this component when 0.5% initial accuracy and extended temperature operation are critical requirements. Consider the through-hole TO-92-3 package constraint against available board space. Evaluate the 100 mA sink current limit against peak load demands in the target application circuit.

Part Context

This part belongs to the TL431 family of three-terminal shunt regulators widely used in power management. The 'B' suffix denotes the 0.5% accuracy grade, while 'QL' specifies the automotive-grade qualification and TO-92 package variant. The 'E3' suffix typically indicates lead-free composition compliant with environmental standards.
