Overview
The TL431ACLP-Z is a precision adjustable shunt voltage reference manufactured by Texas Instruments. It operates within an input voltage range of up to 37V and provides an adjustable output voltage from 2.495V to 36V. The device features an initial accuracy of ±1% at 25°C and a maximum temperature coefficient of 92ppm/°C. It supports a sink current capability of up to 100mA and functions within a commercial temperature range of 0°C to +70°C. The component is housed in a TO-92-3 through-hole package.
Feature Summary
- Provides precise adjustable voltage regulation with sharp turn-on characteristics suitable for replacing Zener diodes
- Maintains thermal stability across commercial operating temperatures with low output drift
- Offers high sink-current capability for effective on-board regulation and power supply applications
Applications
- On-board regulation circuits
- Adjustable power supplies
- Switching power supplies
Procurement Notes
Verify the specific suffix 'Z' against the manufacturer's latest documentation to confirm compliance with RoHS directives and REACH standards. Confirm that the TO-92-3 package matches the intended PCB footprint and mounting requirements. Ensure the ±1% accuracy grade meets the circuit design specifications before finalizing procurement.
Selection Notes
Select this component when a standard-grade (±1%) adjustable shunt regulator is required for commercial temperature environments. It is suitable for designs needing an output voltage between 2.495V and 36V with a maximum sink current of 100mA. Consider alternative grades if tighter tolerance or extended industrial temperature ranges are necessary.
Part Context
This part belongs to the TL431 family of three-terminal programmable shunt regulators. These devices are widely used as voltage references in various electronic systems. The TL431ACLP-Z specifically denotes the A-grade accuracy variant packaged in a TO-92 case, distinguishing it from other packages like SOT-23 or PDIP variants within the same product line.
Replacement Considerations
Direct substitutes include TL431ACLPR and TL431ACLP. Verify pinout compatibility and package dimensions when transitioning between bulk and tape-and-reel packaging options.
