SLVS139W – JULY 1996 – REVISED MARCH 2018 TLV431x 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 any
value between VREF (1.24 V) and 6 V with two
external resistors (see the Parameter Measurement
Information section). These devices operate from a
lower voltage (1.24 V) than the widely used TL431
and TL1431 shunt-regulator references. 1 Low-Voltage Operation, VREF = 1.24 V
Adjustable Output Voltage, VO = VREF to 6 V
Reference Voltage Tolerances at 25В°C
– 0.5% for TLV431B
– 1% for TLV431A
– 1.5% for TLV431
Typical Temperature Drift
– 4 mV (0В°C to 70В°C) …
