Overview
The TLVH432BIDBZR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of up to 18 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±0.5% 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 functions reliably across an extended temperature range from -40°C to +85°C and 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 systems
- Compact three-terminal SOT-23 surface-mount packaging
Applications
- Battery-operated equipment requiring precise voltage references
- Portable devices utilizing low-voltage power supplies
- General-purpose voltage reference circuits in consumer electronics
Procurement Notes
Verify the complete part number including suffixes such as G4 or specific tape-and-reel configurations against official Texas Instruments documentation. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity matches the manufacturer's standard packaging specifications to avoid handling discrepancies during procurement.
Selection Notes
Select this component when a low-voltage, high-accuracy reference is required in a small footprint. Compare the 70 mA cathode current capability against load requirements. Evaluate the 138 ppm/°C temperature coefficient against thermal stability needs. Consider the SOT-23-3 package constraints for PCB layout and thermal dissipation relative to similar family members like the TLVH431 series.
Part Context
This device belongs to the TLVH432 family of low-voltage adjustable precision shunt regulators. It serves as a direct replacement for legacy TL432 components in designs where lower supply voltages are utilized. The family shares functional similarities with the TLVH431 series but offers higher maximum output voltage capabilities. It is designed for applications demanding precision in space-constrained, low-power environments.
Replacement Considerations
Publicly confirmed substitute part numbers include TLVH432BIDZT and TLVH432BIDVRG4. Verify pin compatibility and electrical parameter alignment before substitution.
