Overview
The TL431ACDBVRG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495V to 36V and supports a maximum output current of 100mA. The device features an initial accuracy of ±1% and a maximum temperature coefficient of 92ppm/°C. Designed for surface mount applications, it utilizes a 5-pin SOT-23 package (SC-74A). The component is RoHS compliant and classified under EAR99. It functions as a versatile voltage reference suitable for power management circuits requiring stable regulation.
Feature Summary
- Provides adjustable voltage reference functionality with high precision
- Utilizes compact SOT-23 surface mount packaging for space-constrained designs
- Ensures stable performance across operating temperatures with low drift characteristics
Applications
- Adjustable power supply regulation
- Voltage reference in switching mode power supplies
- Comparator replacement in analog signal processing
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the latest manufacturer documentation. Confirm the active lifecycle status as sources indicate potential obsolescence or transition to alternative part numbers like TL431ACDBVR. Ensure compatibility with automated assembly processes given the tape and reel packaging format specified in official datasheets.
Selection Notes
Select this component when a precise, adjustable shunt regulator is required in a small footprint. The ±1% initial accuracy makes it suitable for applications demanding tight voltage tolerance. Consider the thermal performance and operating temperature range relative to the system environment. Verify that the cathode current requirements align with the circuit design constraints.
Part Context
This device belongs to the TL431 family of programmable zener diodes, widely used as voltage references and error amplifiers. The TL431 series is known for its replaceability of fixed voltage zeners with adjustable versions. The DBVR suffix denotes the specific SOT-23-5 package variant optimized for surface mount technology, distinguishing it from through-hole or larger package options.
Replacement Considerations
Direct substitute part numbers include TL431ACDBVR. Other compatible alternatives may include TL431ACD or TL431AW5 depending on package and specification requirements.
