Overview
The TLVH432BCDBZT is a low-voltage adjustable precision shunt regulator from Texas Instruments, housed in an SOT-23-3 surface-mount package. It features an initial accuracy of ±0.5% and operates with a maximum input voltage of 20 V. The device supports an adjustable output range up to 18 V, with a minimum cathode current of 80 µA and a maximum shunt current of 80 mA. It functions within a temperature range of -40°C to +125°C and exhibits a temperature coefficient of 138 PPM/°C.
Feature Summary
- Provides high-precision voltage regulation with ±0.5% initial accuracy for stable reference applications.
- Operates effectively at low voltages with a maximum input rating of 20 V.
- Designed for wide industrial temperature environments ranging from -40°C to +125°C.
Applications
- Battery-powered equipment requiring precise low-voltage references
- Portable consumer electronics utilizing compact SOT-23-3 packaging
- Industrial control systems needing wide temperature stability
Procurement Notes
Verify the specific suffix 'B' indicates the ±0.5% accuracy grade distinct from other variants. Confirm the 'Q' designation if automotive qualification is required, as this part number lacks it. Ensure the SOT-23-3 package matches the PCB footprint. Check RoHS compliance status via official documentation before integration.
Selection Notes
Select this component when ±0.5% accuracy is necessary alongside low-voltage operation up to 20 V. Compare against TLVH432IDBZT if lower cost with 1.5% accuracy suffices. Consider TLVH432BQDBZR for automotive-grade requirements. Evaluate thermal performance within the -40°C to +125°C range for the specific application environment.
Part Context
This device belongs to the TLVH432 family of low-voltage adjustable precision shunt regulators. It serves as a direct replacement for standard TL432 devices in space-constrained designs. The family offers various accuracy grades and package options to suit different power management needs in portable and industrial sectors.
Replacement Considerations
TLVH432BQDBZR is a confirmed automotive-grade alternative within the same series. TLVH432IDBZT offers similar functionality with reduced accuracy specifications.
