AS13985F30_EK_ST belongs to a type of linear voltage regulators which is able to provide precise output voltage through regulating an input voltage. This application is typically used for systems that require an output voltage that is constant even when the input voltage might fluctuate, as it is the case for many modern electronic systems.

AS13985F30_EK_ST linear voltage regulator benefits include high accuracy, low dropout voltage, low quiescent current, high-temperature operation, and the ability to provide stable output voltage even when the input voltage varies significantly. The device is typically used in precision circuits to regulate the supply voltage of sensitive components such as amplifiers, microphones, LCDs, and embedded processors.

The working principle of AS13985F30_EK_ST linear voltage regulator is based on a three-terminal voltage regulator system insulated gate bipolar transistors (IGBTs) being connected in series with a regulating element. A variable output voltage is obtained by varying the size of the IGBTs. When the input voltage increases, the IGBTs will increase their size and hence increase the output voltage. Similarly, when the input voltage decreases, the size of the IGBTs is also reduced, thus lowering the output voltage.

The output voltage is regulated by a feedback network which monitors the output voltage and compares it to a reference voltage. If the detected output voltage falls below the reference voltage, the feedback signal will increase the size of the IGBTs, increasing the output voltage until it matches the reference voltage. Similarly, if the detected output voltage exceeds the reference voltage, the size of the IGBTs will be decreased, lowering the output voltage.

As the voltage regulator is based on IGBTs, it can provide a very accurate output voltage with virtually no variation under changing load conditions. Furthermore, the output voltage is well protected against transient over-voltage or short circuit. AS13985F30_EK_ST is the ideal choice for applications that require a precisely regulated output voltage with a wide operating range.

Since the device is mostly used in precision circuits, a high temperature operation is very important. AS13985F30_EK_ST can operate with junction temperatures ranging from -40°C to +150°C. This wide operating range makes it suitable for wide range of applications such as automotive, industrial, and consumer electronics.

Another key feature of AS13985F30_EK_ST is its low quiescent current. The low quiescent current ensures that the device consumes very low current even when it is not in use. This makes AS13985F30_EK_ST ideal for battery operated systems where the battery life is extended due to the low current draw.

In conclusion, AS13985F30_EK_ST is a linear voltage regulator which belongs to the Evaluation Board - Linear Voltage Regulators family. Its main features include high accuracy, low dropout voltage, low quiescent current, high-temperature operation, and the ability to provide stable output voltage even when the input voltage varies significantly. Furthermore, its wide operating range and low quiescent current makes it an ideal choice for high accuracy systems.
