Overview
The TLV431IDBVTG4 is a low-voltage adjustable precision shunt regulator from Texas Instruments, housed in a 5-pin SOT-23 package. It provides an initial accuracy of ±1.5% and supports an output voltage range from 1.24 V to 6 V. The device operates with a maximum cathode current of 15 mA and withstands a maximum reference-to-cathode voltage of 7 V. It functions within a temperature range of -40°C to 85°C and features a temperature coefficient of 138 ppm/°C.
Feature Summary
- Adjustable output voltage capability spanning 1.24 V to 6 V
- Precision regulation with ±1.5% initial accuracy
- Low-voltage operation suitable for battery-powered applications
Applications
- Battery-operated equipment requiring precise voltage references
- Programmable linear regulators
- Voltage supervisors and window comparators
Procurement Notes
Verify the complete part number including suffixes such as 'TG4' to ensure compliance with specific packaging and environmental standards like RoHS. Confirm that the required operating temperature range aligns with the specified -40°C to 85°C limit. Ensure circuit design accommodates the 15 mA maximum cathode current and 7 V maximum voltage rating to prevent device damage during operation.
Selection Notes
Select this component when a compact surface-mount solution is required for low-voltage precision regulation. The SOT-23-5 package offers space efficiency compared to larger packages. Consider the ±1.5% accuracy tolerance against application requirements; higher precision variants may be necessary if tighter tolerances are critical for system performance.
Part Context
This device belongs to the TLV431 family of adjustable precision shunt regulators. It serves as a cost-effective alternative to Zener diodes, offering superior stability and lower dynamic impedance. The family includes various accuracy grades and package options, with this specific variant optimized for general-purpose low-voltage applications requiring reliable reference performance.
Replacement Considerations
Compatible substitutes include the TLV431AIDBVTG4 (±1% accuracy) and TLV431BIDBVTG4 (±0.5% accuracy). Other pin-compatible options from different manufacturers should be evaluated for matching electrical characteristics and thermal specifications.
