description/ordering information

The TLV431, TLV431A, and TLV431B are low-voltage 3-terminal adjustable voltage references with specified

thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to

any value between V

(1.24 V) and 6 V with two external resistors (see Figure 2). These devices operate from

REF

a lower voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references.

When used with an optocoupler, the TLV431, TLV431A, and TLV431B are ideal voltage references in isolated

feedback circuits for 3-V to 3.3-V switching-mode power supplies. These devices have a typical output

impedance of 0.25 Ω. Active output circuitry provides a very sharp turn-on characteristic, making the TLV431,

TLV431A, and TLV431B excellent replacements for low-voltage Zener diodes in many applications, including

on-board regulation and adjustable power supplies.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
