Overview
The TLVH431CDBZTG4 is a low-voltage adjustable precision shunt regulator from Texas Instruments, housed in a 3-pin SOT-23 (DBZ) package. It features an initial accuracy of 1.5% and supports a maximum cathode current of 80 mA with a minimum regulation current of 60 uA. The device operates within a temperature range of 0°C to 70°C and accepts a maximum series reference input voltage of 20 V.
Feature Summary
- Adjustable output voltage capability for flexible circuit design
- Low-voltage operation suitable for battery-powered applications
- Precision regulation with defined initial accuracy specifications
Applications
- Battery-operated equipment requiring precise voltage references
- Portable devices utilizing low-voltage power supplies
- General-purpose voltage regulation in compact form factors
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the operating temperature range matches the application requirements, as this variant specifies 0°C to 70°C. Ensure the SOT-23 package dimensions align with the PCB footprint constraints during procurement planning.
Selection Notes
Select this component when a low-cost, adjustable shunt regulator is required for low-voltage systems. The 1.5% accuracy and 80 mA current capacity suit general regulation tasks. Consider the 0°C to 70°C operating range; if wider industrial temperatures are needed, evaluate other variants within the TLVH431 family that support -40°C to 125°C ranges.
Part Context
This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to fixed voltage references, offering adjustability from approximately 1.24 V up to the maximum input limit. The DBZ package provides a compact solution for space-constrained designs.
Replacement Considerations
Direct substitutes include other TLVH431 variants with compatible packages and electrical characteristics. Verify temperature range compatibility, as some family members operate from -40°C to 125°C. Ensure pinout and package dimensions match for direct replacement without PCB redesign.
