TLVH432QDBZT

Overview

The TLVH432QDBZT is an adjustable precision shunt voltage reference from Texas Instruments, housed in a SOT-23-3 surface-mount package. It operates within a supply voltage range up to 20 V and provides an adjustable output voltage up to 18 V. The device features an initial accuracy of 1.5% and a temperature coefficient of 138 PPM/°C. It supports a maximum shunt current of 80 mA with a minimum operating cathode current of 80 µA. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

Adjustable precision shunt regulation architecture
Extended industrial temperature operation capability
Low-voltage compatible design

Applications

Battery-powered equipment voltage monitoring
Portable instrumentation reference circuits
Automotive sensor signal conditioning

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification requirements against your system specifications. Confirm the SOT-23-3 package dimensions match your PCB footprint constraints. Ensure the 1.5% initial accuracy meets your circuit tolerance needs. Validate that the 80 mA maximum shunt current is sufficient for your load conditions. Check RoHS compliance status for environmental regulations.

Selection Notes

Select this component when automotive-grade reliability is required alongside low-voltage operation. Compare the 138 PPM/°C temperature coefficient against stricter stability needs where other series variants may be preferable. Consider the SOT-23-3 package size limitations for high-current applications. Evaluate the 1.5% initial accuracy against tighter tolerance requirements found in higher-grade variants.

Part Context

This part belongs to the TLVH432 family of low-voltage adjustable shunt regulators designed for space-constrained applications. It shares architectural similarities with the TLVH431 but offers specific electrical characteristics suited for automotive and industrial environments. The Q suffix typically denotes qualification standards distinct from standard commercial grades within the manufacturer's portfolio.
