Product Summary
The TLV431BIDBZR 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. The TLV431BIDBZR operates from a lower voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references. When used with an optocoupler, the TLV431BIDBZR is an ideal voltage reference in isolated feedback circuits for 3-V to 3.3-V switching-mode power supplies. The TLV431BIDBZR has a typical output impedance of 0.25 Ω.
