TLVH431QLPR

Overview

The TLVH431QLPR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 18 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±1.5% and a temperature coefficient of 138 PPM/°C. It supports a maximum cathode current of 70 mA with a minimum operating current of 100 µA. The component is housed in a TO-92-3 through-hole package and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

Provides stable reference voltage with high initial accuracy for precision applications
Operates at low voltages starting from 2.5 V, suitable for battery-powered systems
Wide operating current range allows flexibility in circuit design
Extended temperature rating ensures reliability in harsh environments

Applications

Portable equipment requiring low-voltage power management
Battery-operated devices needing precise voltage regulation
General-purpose voltage references in industrial control systems
Power supply feedback loops for linear regulators

Procurement Notes

Verify the specific suffix QLPR corresponds to the TO-92-3 through-hole package and ±1.5% accuracy grade. Confirm RoHS compliance status as indicated in official documentation. Check for any product discontinuance notifications or lifecycle changes prior to finalizing procurement decisions to ensure long-term availability.

Selection Notes

Select this component when a through-hole solution is required for low-voltage precision regulation. Compare against SMD alternatives like TLVH431AQDBVR if board space is limited. Ensure the 70 mA cathode current meets load requirements. Verify that the 138 PPM/°C temperature coefficient aligns with system thermal stability needs.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable shunt regulators. It serves as a drop-in replacement for standard TL431 devices in low-voltage applications where lower input voltage operation is necessary. The family offers various packages and accuracy grades to suit different manufacturing and performance constraints.
