Overview
The TLVH431QDBZTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range up to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 1% and a maximum temperature coefficient of 138 PPM/°C. It supports a maximum shunt current of 80 mA with a minimum operating current of 80 uA. The component functions reliably across a temperature range of -40°C to +125°C and is housed in a surface-mount SOT-23-3 package.
Feature Summary
- Provides precise voltage regulation with 1% initial accuracy for stable reference applications
- Operates at low voltages with an adjustable output range suitable for modern electronic systems
- Designed for automotive environments with extended temperature capability and robust performance
Applications
- Automotive power management circuits requiring precise voltage references
- Low-voltage adjustable shunt regulator implementations
- Precision voltage monitoring and control systems
Procurement Notes
Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the SOT-23-3 package type matches the design requirements. Ensure the automotive-grade qualification aligns with the target application environment. Cross-reference the datasheet for any updates on recommended operating conditions.
Selection Notes
Select this component when a low-voltage, high-accuracy shunt regulator is required for automotive or industrial use. Consider the 1% initial accuracy and 138 PPM/°C temperature coefficient for precision needs. Evaluate the 80 mA maximum shunt current against load requirements. Compare against standard TLVH431 variants if automotive qualification is not strictly necessary.
Part Context
This part belongs to the TLVH431 series of low-voltage adjustable precision shunt regulators. It is specifically qualified for automotive applications, distinguishing it from commercial variants. The QDBZR suffix denotes the automotive grade and SOT-23-3 packaging configuration provided by Texas Instruments.
Replacement Considerations
The TLVH431AQDBZT is listed as an alternative within the same product family. Verify functional equivalence regarding voltage ranges and accuracy specifications before substitution.
