Product Summary

The TLV431BIDBZR is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over applicable industrial and commercial temperature ranges. The TLV431BIDBZR operates from a lower voltage (1.24V) 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.

Parametrics

TLV431BIDBZR absolute maximum ratings: (1) Cathode voltage, VKA: 7V; (2) Continuous cathode current range, IK: -20 to 20mA; (3) Reference current range, Iref: -0.05 to 3mA; (4) Operating virtual junction temperature: 150°C; (5) Storage temperature range, Tstg: -65 to 150°C.

Features

TLV431BIDBZR features: (1) Low-Voltage Operation VREF=1.24V; (2) Adjustable Output Voltage, Vo= VREF to 6V; (3) Typical Temperature Drift; (4) Low Operational Cathode Current: 80μA Typ.; (5) 0.25Ω Typical Output Impedance; (6) Ultra-Small SC-70 Package Offers 40%
Smaller Footprint Than SOT-23-3.
