TLV431AI, PME3 are two independent precision programmable, three-terminal shunt regulators known as voltage reference IC, belonging to PMIC (power management integrated circuit) category. Installed in various applications due to their compact size, low cost and high accuracy, these IC’s are mainly used to provide stable and adjustable output voltage to electronic circuits.

As a voltage reference IC, TLV431AI, PME3 have a wide range of applications which cover, data processing, communications equipment, consumer electronics, automotive, and industrial control, etc. They are also applicable in any situation where a reference voltage with tight tolerance and low temperature drift is needed.

The working principle of TLV431AI, PME3 is fairly simple. Both of the regulators have an internal adjustable voltage reference and a temperature-compensated series resistor. The internal reference voltage is compared to an external, adjustable teminateal. If the terminal voltage exceeds the reference voltage, the compensation resistor matches it and the internal switch becomes active. This dynamic regulation ensures that the voltage remains accurately regulated and independent of any variations in external current drawn.

The TLV431AI and PME3 also have some important features that make them even more versatile. For example, the TLV431AI and PME3 are both reverse polarity protected, which ensures that the voltage can never accidentally be set to the wrong level and cause damage. Furthermore, the TLV431AI and PME3 can be programmed through an external voltage, which can be used to adjust the output voltage without ever having to open the device.

Overall, with their simple yet reliable working principle and numerous features, TLV431AI, PME3 are hugely helpful and cost-effective solutions to many applications. Their features make them suitable for use in a variety of projects, from low power consumer electronics to high precision industrial control solutions.
