TLV431 - Low Voltage Adjustable Precision Shunt Regulator
Description/Ordering Information The TLV431 is a low voltage 3 terminal with specified thermal stability, adjustable voltage reference over the applicable industrial and commercial temperature range. The output voltage can be set to any value between VREF
(1.24 V) and 6 two external resistors five. These devices operate at low voltages (1.24 V) as referenced by the more widely used TL431 and TL1431 shunt regulators.
When used with optocouplers, the TLV431 is an ideal 3-V to 3.3-V switch-mode power supply with a voltage reference in isolated feedback circuits. These devices have a typical output impedance of 0.25Ω. Active output circuits offer a very sharp turn-on characteristic, making them excellent alternatives to low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies.
