Overview
The TLVH432ACDBZR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 18 V with an initial accuracy of ±1%. The device supports a cathode current up to 70 mA and functions across a temperature range of -40°C to 125°C. Packaged in a SOT-23-3 surface-mount case, it serves as a compact reference solution for power management circuits requiring stable voltage regulation.
Feature Summary
- Adjustable output voltage capability spanning from 1.24 V to 18 V
- High initial accuracy of ±1% ensures precise voltage referencing
- Low-voltage operation optimized for battery-powered applications
- All-capacitor stability eliminates the need for external components
Applications
- Battery-powered equipment requiring precise voltage monitoring
- Portable devices utilizing low-voltage power supplies
- General-purpose voltage references in compact electronics
- Power management systems needing stable shunt regulation
Procurement Notes
Verify the specific suffix 'AC' denotes the ±1% accuracy grade and industrial temperature range (-40°C to 125°C). Confirm the package type is SOT-23-3 and the component is RoHS compliant. Ensure the ordering part number matches the exact manufacturer designation to avoid functional discrepancies in low-voltage designs.
Selection Notes
Select this component when a low-voltage adjustable reference is required with high accuracy. It is suitable for designs where space is limited due to the small SOT-23-3 footprint. Consider the 70 mA cathode current limit for load requirements. Verify compatibility with the system's operating temperature range before integration into the final product design.
Part Context
This device belongs to the TLVH432 family of low-voltage adjustable precision shunt regulators. It shares architectural similarities with other TLVH43x variants but is specifically optimized for lower voltage operations compared to standard 36 V references. The family provides a cost-effective solution for portable electronics and battery-operated systems requiring reliable voltage regulation.
Replacement Considerations
Direct substitutes include TLVH432AQDBZR for automotive-grade applications or TLVH432AIDBZR for extended industrial specifications. Cross-reference with TL432 series parts if higher voltage tolerance is acceptable, though electrical characteristics may differ significantly.
