description
The TL431 is a three-terminal adjustable shunt
regulator with specified thermal stability over
applicable automotive temperature ranges. The output voltage can be set to any value between Vref
(approximately 2.5 V) and 36 V, with two external resistors (see Figure 17). This device has a typical output
impedance of 0.2
. Active output circuitry provides a sharp turn-on characteristic, making this device an
excellent replacement for Zener diodes in many applications, such as onboard regulation, adjustable power
supplies, and switching power supplies.
