<h2>R7004003XXUA Application Field And Working Principle</h2>R7004003XXUA is an ultra-fast, ultra-low dropout linear regulator designed for a wide range of applications such as a variety of handheld electronics and portable device power. It belongs to the category of Diodes - Rectifiers - Single.In theory, the linear voltage regulator contains a voltage source (Vref) and a series of pass elements. In terms of the R7004003XXUA, it is composed of an internal voltage feedback reference, an error amplifier, an avalanche protected low-side FET (Field-Effect Transistor) switch, and an integrated current limit circuit. The first section of the linear regulator, the voltage reference, has a stable output voltage. In the R7004003XXUA, it is 1.2V by setting an external resistor, potentially providing a very accurate voltage regulation in a given input voltage range.The second section is an error amplifier, which is an operational amplifier configured to amplify the difference between the input voltage and the voltage reference and regulates the output voltage accordingly. In the R7004003XXUA, it is made up by an amplifier combined with a transistor which gives the amplifier a very wide gain bandwidth. Third is the switch section consisting of an avalanche protected low-side FET which is the core of the linear regulator. It is responsible for providing the output voltage. Fourth is the current limit section. It limits the current to the output so that it won\'t exceed the rated current.Overall, the linear regulator like the R7004003XXUA has the main advantage of being able to provide high accuracy over a wide temperature and input voltage range. Its performance is also not affected by output capacitors, making it ideal for a variety of applications.<h2>Key Features of R7004003XXUA</h2>The key features of R7004003XXUA include:• Low Dropout Voltage: ultra-low 0.18V at light load. • Wide Input Voltage Range: 1.8V to 5.5V. • Low Quiescent Current: 100uA operating current and 0.2uA standby current. • High Output Accuracy: +/- 1% voltage accuracy on the 1.2V setting. • Maximum Output Current: 1A. • Temperature Range: -40°C to 85°C. • Stable with a variety of output capacitors. • Excellent line and load regulation. • OverCurrent Protection. • Low-Noise Operation<h2>Applications Of R7004003XXUA</h2>The R7004003XXUA is suitable for a wide range of applications and primarily used in products such as handheld electronic equipment, digital audio players, portable gaming equipment and other devices operating on 1.2V.
