Overview
The TL431CLPE3 is an adjustable precision shunt regulator from Texas Instruments, housed in a TO-92 package. It provides an output voltage range of 2.5V to 36V with an initial accuracy of ±0.4%. The device operates within a temperature range of 0°C to 70°C and supports a maximum cathode current of 100mA. It features a low dynamic impedance and requires a minimum operating current of 1mA for regulation.
Feature Summary
- Provides precise adjustable voltage reference functionality
- Features low dynamic impedance for stable regulation
- Designed for through-hole mounting applications
Applications
- Precision power supply regulation
- Voltage reference circuits
- Comparator replacement
Procurement Notes
Verify the specific suffix 'E3' indicates RoHS compliance and lead-free construction. Confirm the package type matches the required PCB footprint. Check for active status or obsolescence notices as TI may update product lines. Ensure the ±0.4% accuracy grade meets the design tolerance requirements.
Selection Notes
Select this component when high accuracy is required compared to standard TL431 variants. The TO-92 package suits prototyping and low-volume through-hole designs. Consider thermal dissipation limits if operating near maximum current ratings. Verify compatibility with existing circuit biasing networks.
Part Context
This part belongs to the TL431 family of programmable shunt regulators. It serves as a versatile alternative to Zener diodes, offering superior stability and temperature performance. The device integrates a 2.5V internal reference with error amplifier and output transistor.
