Overview
The ATL431EAIDBZR is an adjustable shunt voltage reference integrated circuit manufactured by Texas Instruments. It operates within a cathode-to-anode voltage range of 2.5V to 36V and provides an initial accuracy of ±0.5%. The device features a temperature coefficient of 48ppm/°C and supports a maximum cathode current of 100mA with a minimum operating current of 100µA. It is housed in a SOT-23-3 surface-mount package and functions across a temperature range of -40°C to 85°C.
Feature Summary
- Adjustable shunt regulation architecture for precise voltage referencing
- High initial accuracy of ±0.5% for enhanced precision applications
- Capacitor-stable design ensuring reliable operation without external compensation components
Applications
- Precision power supply feedback loops
- Programmable linear regulators
- Battery management systems
Procurement Notes
Verify the specific suffix 'E' against official Texas Instruments documentation to confirm it denotes the ±0.5% accuracy grade, as standard variants may differ. Ensure the ordering part number matches the exact thermal and electrical specifications required for the target application environment.
Selection Notes
Select this component when high initial accuracy is critical compared to standard ±1% or ±2% alternatives. The SOT-23-3 package offers space efficiency for compact designs. Consider the 100mA output capability for driving moderate loads directly within regulator circuits.
Part Context
This part belongs to the ATL431 family of adjustable shunt regulators from Texas Instruments. It serves as a high-precision alternative to standard TL431 devices, offering tighter tolerance specifications while maintaining compatibility with common reference circuit topologies and pinouts.
