TL431 Function Overview

Description
The TL431 is a programmable shunt voltage reference with guaranteed temperature stability over the entire operating temperature range.
The output voltage may be set to any value between 2.5 V and 36 V with two external resistors.
The TL431 operates with a wide current range from 1 to 100 mA with a typical dynamic impedance of 0.22 Ω.
Features
■ Adjustable output voltage: 2.5 to 36 V
■ Sink current capability: 1 to 100 mA
■ Typical output impedance: 0.22Ω
■ 1% and 2% voltage precision
