description

CATHODE

REF

The TL431 and TL431A are three-terminal

adjustable shunt regulators with specified thermal

stability over applicable automotive, commercial,

and military temperature ranges. The output

NC – No internal connection

(approximately 2.5 V) and 36 V with two external

resistors (see Figure 17). These devices have a

typical output impedance of 0.2 Ω. Active output

circuitry provides

very sharp turn-on

characteristic, making these devices excellent

replacements for Zener diodes in many

applications, such as onboard regulation,

adjustable power supplies, and switching power

supplies.

The TL431C and TL431AC are characterized for

operation from 0°C to 70°C, and the TL431I and

TL431AI are characterized for operation from

–40°C to 85°C.
