5. Functional diagram

The TL431 family comprises a range of 3-terminal adjustable shunt regulators, with specified

thermal stability over applicable automotive and commercial temperature ranges. The output

voltage can be set to any value between V_ref(approximately 2.5 V) and 36 V with two external

resistors (see Figure 8). These devices have a typical output impedance of 0.2 Ω. Active output

circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements

for Zener diodes in many applications like on-board regulation, adjustable power supplies and

switching power supplies.
