Overview
The TLVH432AQDBZR is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-3 surface-mount package. It operates within a voltage range of 1.24 V to 18 V with an initial accuracy tolerance of ±1%. The device supports a maximum cathode current of 70 mA and maintains operation across a temperature range of -40°C to 125°C.
Feature Summary
- Provides adjustable reference voltage functionality via external resistors
- Ensures high precision with ±1% initial accuracy tolerance
- Designed for robust performance across extended industrial temperature ranges
Applications
- Precision voltage reference circuits
- Portable equipment power management
- Battery-powered system monitoring
Procurement Notes
Verify the specific suffix 'Q' indicates automotive qualification standards when applicable. Confirm the 'DBZR' suffix corresponds to the SOT-23-3 package and tape-and-reel delivery format. Ensure compatibility with RoHS3 compliance requirements for the target assembly process. Cross-reference the manufacturer part number against official datasheets to validate electrical specifications before integration.
Selection Notes
Select this component for applications requiring low-voltage operation up to 18 V with tight accuracy constraints. The SOT-23-3 package suits space-constrained designs. Consider the 70 mA cathode current limit for load driving capabilities. Evaluate thermal performance within the specified -40°C to 125°C operating range for environmental suitability.
Part Context
This device belongs to the TLVH432 family of low-voltage adjustable shunt regulators. It shares architectural similarities with other TI precision references but is optimized for lower voltage domains compared to higher-voltage counterparts like the TL432 series. The family emphasizes compact packaging and reliable performance for modern electronic systems.
Replacement Considerations
TLVH432QDBZT offers similar functionality with potentially different accuracy or current specifications. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official cross-reference guides for validated alternatives.
