TLVH431CDBZT

Overview

The TLVH431CDBZT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 1% 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 functions reliably across an extended temperature range from -40°C to +125°C and is housed in a surface-mount SOT-23-3 package.

Feature Summary

Provides precise programmable reference voltage for low-voltage applications
Offers adjustable output capability within a wide operational range
Ensures stable regulation with high initial accuracy specifications

Applications

Battery-powered equipment requiring precise voltage references
Portable devices utilizing low-voltage power supplies
General-purpose voltage regulation circuits

Procurement Notes

Verify the specific suffix codes against official Texas Instruments documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing design parameters regarding thermal performance and current handling capabilities before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require a compact, low-voltage adjustable reference source. Consider the SOT-23-3 package constraints and the specific accuracy requirements relative to the 1% initial tolerance. Evaluate the thermal management needs given the extended operating temperature range.

Part Context

This part belongs to the TLVH431 family of low-voltage programmable shunt regulators. It serves as a modern alternative to traditional higher-voltage references, specifically optimized for battery-operated systems where supply voltages are limited. The series maintains the functional benefits of precision regulation while reducing power consumption.
