Texas Instruments  TLV431ILP

The TLV431 device is a low-voltage 3-terminal adjustable voltage reference with specifiedthermal stability over applicable industrial and commercial temperature ranges. Output voltage canbe set to any value between VREF (1.24 V) and 6 V with two externalresistors (see the Parameter Measurement Information section). These devicesoperate from a lower voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulatorreferences.

When used with an optocoupler, the TLV431 device is an ideal voltage reference inisolated feedback circuits for 3-V to 3.3-V switching-mode power supplies. These devices have atypical output impedance of 0.25 Ω. Active output circuitry provides a very sharp turnoncharacteristic, making them excellent replacements for low-voltage Zener diodes in manyapplications, including on-board regulation and adjustable power supplies.
