description
The TLV431 and TLV431A are low-voltage
three-terminal adjustable voltage references with
specified
thermal
stability
over
applicable
industrial and commercial temperature ranges.
Output voltage can be set to any value between
Vref (1.24 V) and 6 V with two external resistors
(see Figure 2). The TLV431 and TLV431A 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 and
TLV431A 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
. Active output
circuitry
provides
a
very
sharp
turn-on
characteristic, making the TLV431 and TLV431A
excellent replacements for low-voltage zener
diodes in many applications, including onboard
regulation and adjustable power supplies.
The TLV431C and TLV431AC devices are characterized for operation from 0
°C to 70°C. The TLV431I and
TLV431AI devices are characterized for operation from –40
°C to 85°C.

The LP package is available taped and reeled. Add the suffix R to the device type
(e.g., TLV431ACLPR). The D and DBV are available only taped and reeled (e.g.,
TLV431IOR). Chip forms are tested at 25
°C.
