description/ordering information

The TLV431 is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over

applicable industrial and commercial temperature ranges. Output voltage can be set to any value between V

REF

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

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

When used with an optocoupler, the TLV431 is an ideal voltage reference 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 them 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.
