SLVS905A – DECEMBER 2008 – REVISED OCTOBER 2017 TLV431x-Q1 Low-Voltage Adjustable Precision Shunt Regulator
1 Features 3 Description The TLV431 device 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
1.24V on stand alone mode or any value between
VREF (1.24 V) and 6 V with two external resistors (see
Figure 23). These devices operate from a lower
voltage (1.24 V) than the widely used TL431 and
TL1431 shunt-regulator references. 1 Qualified for Automotive Applications
AEC-Q100 Qualified With the Following Results:
– Device Temperature Grade 1: -40°C to 125°C
Ambient Operating Temperature Range
Low-Voltage Operation, VREF = 1.24 V
Adjustable Output Voltage, VO = VREF to 6 V
Reference Voltage Tolerances at 25В°C
