Overview
The TL431AILPE3 is a three-terminal adjustable shunt voltage reference manufactured by Texas Instruments in a TO-92 package. It provides an adjustable output voltage ranging from 2.495 V to 36 V using two external resistors. The device features an initial accuracy of ±1% and supports a maximum cathode current of 100 mA with a minimum operating current of 700 µA. It operates within a temperature range of -40°C to 85°C and has a maximum input voltage rating of 37 V.
Feature Summary
- Adjustable output voltage capability between 2.495 V and 36 V via external resistor network
- High precision with ±1% initial accuracy at 25°C
- Low output impedance for stable regulation performance
- Automotive qualification compliant for enhanced reliability
Applications
- Board-level voltage regulation circuits
- Adjustable power supply designs
- Switching power supply feedback loops
- Zener diode replacement applications
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free compliance and RoHS status. Confirm the package type matches the required TO-92 through-hole form factor. Ensure the ±1% accuracy grade meets the circuit tolerance requirements. Check for automotive qualification documentation if used in vehicle electronics.
Selection Notes
Select this component when precise, adjustable voltage referencing is required in compact through-hole designs. The ±1% accuracy suits applications demanding tighter tolerances than standard references. Consider the 100 mA current capacity for driving moderate loads or feedback networks. Verify thermal stability needs against the specified temperature coefficient.
Part Context
This part belongs to the TL431 family of programmable parallel regulators. It serves as a versatile alternative to fixed Zener diodes in linear and switching regulator topologies. The TO-92 package allows for easy prototyping and manual assembly. It is widely used in industrial and consumer electronics for voltage monitoring and control.
Replacement Considerations
TL431AILPR is a tape-and-reel version of the same electrical specification. TL431ACLP offers similar performance but may have different packaging or availability status. Verify pinout compatibility and thermal characteristics before substitution.
