Overview
The ZTL431BFFTA is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within an ambient temperature range of -40°C to +125°C and provides a reference voltage tolerance of 0.5% at +25°C. The device supports an output voltage range from VREF to 20V, determined by external divider resistors. It features a typical dynamic output impedance of 0.2Ω and handles sink currents between 1mA and 100mA. The component utilizes the SOT23F package.
Feature Summary
- Provides adjustable output voltage programmable via external resistor dividers
- Delivers high current handling capability up to 100mA with low dynamic output impedance
- Maintains excellent temperature stability across extended commercial ranges
Applications
- Opto-Coupler Linearization
- Linear Regulators
- Improved Zener Replacement
- Variable Reference Circuits
Procurement Notes
Verify that the specific B grade designation confirms the required 0.5% initial tolerance for your design specifications. Ensure the SOT23F package footprint matches your PCB layout constraints. Confirm RoHS compliance requirements align with your manufacturing standards before finalizing procurement orders.
Selection Notes
Select this component when precise voltage referencing is required in space-constrained designs utilizing the SOT23F package. The 0.5% tolerance grade ensures tighter accuracy compared to standard grades. Consider the maximum cathode voltage rating and operating temperature limits during circuit planning.
Part Context
This part belongs to the ZTL431/ZTL432 series of cost-effective adjustable precision shunt regulators. It serves as a functional equivalent to the TL431/TL432 family, offering improved performance over traditional zener diodes. The 'FF' suffix specifically denotes the SOT23F surface-mount package configuration.
Replacement Considerations
Functionally equivalent to the TL431 series; however, verify pinout compatibility if substituting into existing layouts designed for different package types.
