TL431 Adjustable Shunt Regulator (3 pcs)

QAR 1.00/ unit

Description

TL431 devices are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between V REF , approximately 2.5 V and 36 V, with two external resistors. These devices have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies. Features • 1% Reference voltage tolerance at 25°C • Adjustable output voltage: V REF   to 36 V • Operation from -40°C to +125°C • Typical temperature drift (TL431B) • 6 mV (C temp) • 14 mV (I temp, Q temp) • Low output noise • 0.2 Ω typical output impedance • Sink-current capability: 1 mA to 100 mA
