14.14.TL431

14.14.1.Description

The TL431 is a 3-terminal adjustable shunt voltage regulator providing a highly accurate 1 % band gap
reference. TL431 acts as an open-loop error amplifier with a 2.5V temperature compensation reference.
The TL431 thermal stability, wide operating current (150mA) and temperature range (0.to 105.makes it
suitable for all variety of application that are looking for a low cost solution with high performance. The
output voltage may be adjusted to any value between VREF and 36 volts with two external resistors.
The TL431 is operating in full industrial temperature range of 0°C to 105°C. The TL431 is available in
TO-92, SO-8, SOT-89 and SOT23-5 packages.

14.14.2.Features

• Trimmed Band gap to 1%
• Wide Operating Current
• Extended Temperature Range
• Low Temperature Coefficient
• Offered in TO -92, SOIC, SOT-89, SOT-23-5
• Improved Replacement in Performance for TL431
• Low Cost Solution
