PMIC (Power Management IC) is a semiconductor integrated circuit device that can supply various electrical energy sources and provide the appropriate output to electronic devices. PMICs can be divided into many categories, each with its own specific application field and working principle. Voltage reference is one important category of PMICs. Let\'s take LT1790BCS6-2.5#TRMPBF as an example to explore its application field and working principle.

LT1790BCS6-2.5#TRMPBF is a high precision precision voltage reference designed to generate a precise voltage reference or voltage to current conversion. Its application field can be found in battery operated devices like digital voltmeters, temperature compensation circuits, audio integrated circuits, and temperature sensors. It works primarily as a voltage reference in circuits, providing a stable and precise voltage reference to various analog circuits.

LT1790BCS6-2.5#TRMPBF adopts a bandgap reference circuit to provide a stable output voltage. The so-called bandgap reference circuit is basically an integrated circuit with a matched precision transistor in the positive and negative pairs, which together form a differential amplifier. The amplifier function serves to provide a voltage output across a resistor bridge circuit. This output voltage is then amplified and filtered by a buffer amplifier to realize the stable output we need.

With its high accuracy, stability and low temperature coefficient, LT1790BCS6-2.5#TRMPBF is ideal for applications that require precise and reliable voltage references. Its precision voltage reference output ensures that the voltage reference signal is perfect and is not affected by temperature or component tolerance changes. The voltage reference signal can provide a stable and accurate output voltage, allowing the end device to achieve precise and reliable operation.

In order to better understand how exactly LT1790BCS6-2.5#TRMPBF works in practice, it is essential to understand a few of the basic principles involved. A circuit requires more stable voltage than the voltage it is powered by. To do so, the voltage reference is used to separate the power voltage from the signal voltage. The signal voltage is then buffered by an amplifier, and the resonance point is used to set the output voltage. The LT1790BCS6-2.5#TRMPBF is able to provide a very precise voltage reference, which eliminates the need for external components.

Overall, LT1790BCS6-2.5#TRMPBF is a versatile precision voltage reference designed to generate a precise voltage reference or voltage to current conversion in various analog circuits in battery operated devices. Its application involves both technical and scientific fields, and its relative high accuracy, stability and low temperature coefficient makes it ideal for precision applications. Its working principle revolves around the usage of a band-gap reference circuit, a differential amplifier and a buffer amplifier to generate a stable output voltage.
