- Low noise: ultralow output noise, typically 5 μVrms @ 1kHz
- Thermal protection circuit
- Extremely low temperature coefficient
- High immunity to line and load transients
- Low ripple and high accuracy
- Adjustable output voltage
- High reliability
Application fields
EAN61573601’s wide input range and adjustable output voltage makes it suitable for various applications, such as microprocessor power supply, AC-to-DC power adapter, and point-of-load (PoL) regulator.
EAN61573601 is suitable for microprocessor power supply because of its high immunity to load transients, and its require of very low quiescent current causes very low power consumption. In the application of AC-to-DC power adapter, the device has the advantage of low noise, high power dissipation and improved voltage accuracy up to ±1%. And for PoL applications, EAN61573601 can provide output regulation in line with the requirements of state-of-the-art processors and memory.
Working principle
Linear voltage regulator, as its name implies, can provide a fixed output voltage from a wide input voltage. The regulator utilizes an internal voltage reference, pass element (transistors, diodes) and an error amplifier. The resistors of the external voltages (input and output) are biasing the two passes and the amplifier where the gain of the amplifier is controlled by the feedback resistor.
In operation, the higher voltage of the input is “compared” to the voltage reference, and the error amplifier produces a controlling voltage which will bias the pass element. When the input voltage decreases, the pass element will be turned off, the output voltage will remain at its set level. As the input increases, the pass element will be turned on, thus allowing the current (at a certain level) to flow through, and the output voltage will remain different from the input voltage. The process will then be repeated over and over again until the input voltage stabilizes.
Conclusion
EAN61573601 is a class of linear voltage regulator designed by EAN. It has many features, such as its wide input voltage range, adjustable output voltage, high reliability, etc. This LVR has wide applications in microprocessor power supply, AC-to-DC power adapter, and point-of-load (PoL) regulator. The working principle of a linear voltage regulator is based on the comparison between input and output voltage, and the controlling procedure of the internal elements.
