TLVH431BCLPRE3

Overview

The TLVH431BCLPRE3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It features an adjustable output voltage range from 1.24 V to 18 V with an initial accuracy of ±0.5%. The device operates within a wide current range, supporting a minimum cathode current of 80 µA and a maximum sink current of 80 mA. It is designed for operation over an extended temperature range of -40°C to +125°C. The component utilizes a TO-92-3 through-hole package and exhibits a typical dynamic impedance of 0.22 Ω.

Feature Summary

• Provides precise voltage regulation with ±0.5% initial accuracy across the operating temperature range.
• Supports low-voltage operation with an adjustable reference output spanning 1.24 V to 18 V.
• Enables design flexibility through a wide operating current range suitable for power-constrained applications.

Applications

• Battery-operated equipment requiring stable voltage references
• Switch-mode power supplies
• Data acquisition systems

Procurement Notes

Verify the specific suffix CLP against the manufacturer's latest documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the assembly process. Ensure the selected variant matches the required thermal performance specifications for the intended operating environment.

Selection Notes

Select this component when a low-voltage adjustable reference with high precision is required in a through-hole package. The ±0.5% accuracy makes it suitable for applications demanding tight voltage tolerances. Consider the TO-92-3 form factor for designs prioritizing manual assembly or legacy board layouts over surface-mount alternatives.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a direct functional replacement for standard TL431 devices but offers optimized performance at lower supply voltages. The family is widely used in general-purpose power management circuits where space and efficiency are critical constraints.

Replacement Considerations

The TLVH431BQLPR is listed as an upgrade alternative within the same product family. Verify electrical parameter equivalence before substitution.
