Overview
The TL431ACDCKTE4 is a programmable shunt voltage reference IC manufactured by Texas Instruments. It operates within an input voltage range of 2.50V to 36.0V and provides an adjustable output voltage from 2.495V to 36V. The device supports a maximum output current of 100 mA with a typical cathode current of 600 µA. It features a tight tolerance of ±1% and maintains operation across a temperature range of 0°C to 70°C. The component is housed in a surface-mount SC-70-6 package.
Feature Summary
- Provides precise, adjustable voltage referencing via external resistor divider
- Operates as a low-cost alternative to Zener diodes for regulation
- Features fast transient response characteristics for dynamic loads
Applications
- Precision voltage references in power supply circuits
- Voltage regulation in portable electronic devices
- Battery-powered equipment requiring stable reference voltages
Procurement Notes
Verify the specific suffix TE4 indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status matches project requirements. Check manufacturer lifecycle status as this part may be discontinued or subject to replacement notices. Ensure the SC-70-6 footprint aligns with PCB design constraints before procurement.
Selection Notes
Select this component when a compact surface-mount solution is required for precision voltage regulation. The ±1% tolerance suits applications demanding higher accuracy than standard Zener diodes. Consider the SC-70-6 package size for space-constrained designs. Evaluate thermal performance within the specified operating temperature range for the intended environment.
Part Context
This device belongs to the TL431 family of programmable shunt regulators. It serves as a versatile reference element in linear and switching power supplies. The SC-70-6 variant offers a smaller footprint compared to traditional SOIC packages, facilitating miniaturization in modern electronics while maintaining electrical performance standards.
Replacement Considerations
Direct substitutes include TL431ACCT and TL431AICT from STMicroelectronics. Verify pinout compatibility and electrical specifications match before substitution.
