Design & Procurement Notes
Designers using TL431CL5T should confirm that the circuit maintains the 1 mA cathode current and that the adjustable output remains within the 2.495 V reference value and 36 V maximum. The 100 mA output current should be considered when selecting the shunt operating point, load conditions, and design margin. The ±2.21% reference tolerance should be accounted for in output voltage accuracy and feedback error budgets. The 0°C to 70°C operating temperature range should be considered for ambient thermal conditions. Because the part uses a SOT-23-5 package, layout and footprint compatibility should be reviewed.
