SLVS555K – NOVEMBER 2004 – REVISED SEPTEMBER 2016 TLVH431, TLVH432 Low-Voltage Adjustable Precision Shunt Regulators
1 Features 3 Description The TLVH431 and TLVH432 devices 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 VREF (1.24 V) and
18 V with two external resistors (see Figure 19).
These devices operate from a lower voltage (1.24 V)
than the widely used TL431 and TL1431 shuntregulator references. 1 Low-Voltage Operation: Down to 1.24 V
Reference Voltage Tolerances at 25В°C
– 0.5% for B Grade
– 1% for A Grade
– 1.5% for Standard Grade
Adjustable Output Voltage, VO = VREF to 18 V
Wide Operating Cathode Current Range:
100 ОјA to 70 mA …
