TLVH432BQDBZTG4

Overview

The TLVH432BQDBZTG4 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 up to 18 V. The device features an initial accuracy of 0.5% and a maximum temperature coefficient of 138 PPM/C. It supports a cathode current range from 80 uA to 80 mA. Designed for robust performance, it functions across a temperature range of -40 C to +125 C. The component is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Adjustable precision shunt regulation with high initial accuracy
• Low-voltage operation suitable for battery-powered applications
• Wide operating temperature range for industrial environments

Applications

• Battery-operated equipment requiring precise voltage monitoring
• Portable devices needing low-power reference solutions
• Industrial control systems utilizing shunt regulation

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the SOT-23-3 package type matches your PCB footprint requirements. Ensure the 20 V maximum input voltage aligns with your circuit design limits. Check for automotive qualification markings if required for your application environment. Validate that the 80 mA maximum cathode current meets your load demands.

Selection Notes

Select this component when low-voltage precision regulation is critical. It is suitable for designs where space is limited due to the small SOT-23-3 package. Consider its 0.5% initial accuracy for applications demanding tight voltage tolerances. Evaluate the 138 PPM/C temperature coefficient against your thermal stability needs. Ensure the 80 uA minimum cathode current requirement can be maintained in your circuit topology.
