Overview
The TLVH431BQDBZRG4 is a low-voltage adjustable precision shunt regulator from Texas Instruments, housed in an SOT-23-3 package. It operates with a maximum input voltage of 7 V and supports an adjustable output range up to 6 V. The device features an initial accuracy of 0.5% and a temperature coefficient of 138 PPM/C. It functions within a junction temperature range of -40°C to +125°C, drawing a minimum cathode current of 80 µA and supporting a maximum cathode current of 15 mA.
Feature Summary
- Provides adjustable precision voltage reference functionality suitable for low-voltage applications
- Ensures stable regulation across extended industrial temperature ranges
- Delivers high initial accuracy for precise circuit control
Applications
- Battery-powered portable devices requiring low supply voltage
- Industrial control systems utilizing programmable power supplies
- Communication equipment needing stable reference voltages
Procurement Notes
Verify the specific suffix G4 indicates RoHS compliance and green material status as per manufacturer documentation. Confirm the SOT-23-3 package dimensions match your PCB footprint requirements. Ensure the operating voltage does not exceed the 7 V maximum limit. Check for any recent PCN notices regarding manufacturing site changes or material updates before finalizing procurement.
Selection Notes
Select this component when a low-voltage adjustable shunt regulator is required with high accuracy. Compare against standard TL431 variants if higher input voltage tolerance is needed. Consider the 15 mA current limit for load driving capabilities. Verify thermal performance within the specified -40°C to +125°C range for your specific environment.
Part Context
This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It shares functional similarities with other TLV431 series components but is optimized for lower input voltage operations. The Q designation typically implies automotive qualification standards, while the RG4 suffix denotes reel packaging with specific environmental compliance.
Replacement Considerations
TLVH431BQDBZR is the non-reel variant of the same component. TLV431BQDBZRG4 offers similar functionality but may differ in specific low-voltage optimization parameters.
