MIC5318-4.6YD5-TR

The MIC5318 is a highly efficient, integrated, low dropout linear voltage regulator. It provides power for a wide variety of electronic applications, such as medical, industrial, and consumer electronics. The MIC5318 is a three-terminal device that features a wide input voltage range of 4.6V to 18V, and output voltage range of 0.8V to 15V. The MIC5318 is designed to be a very low noise and very low power solution that can be used in many applications such as battery-powered portable audio, MP3 players, digital still cameras, cell phones, and other applications that require precision, low-current regulation.

The MIC5318 uses a P-channel MOSFET to act as a "power amplifier" in order to keep the output voltage stable. The MOSFET is part of a circuit controlled by an internal voltage reference and feedback loop. This control circuit senses the output voltage and compares it to the reference voltage. If the output voltage deviates from the reference voltage, the MOSFET is adjusted until the output voltage matches the reference voltage, thus maintaining a constant output voltage. The MIC5318 has a short-circuit protection design that keeps it from overheating, allowing for safe operation.

The MIC5318 has several features that make it well suited for power applications. It provides good line and load regulation, a low dropout voltage, and high power supply rejection. Additionally, the MIC5318 has an adjustable output voltage from 0.8V to 15V, which allows the designer to accommodate different voltage levels in the same application without external components. The MIC5318 also has a low input and output on-resistance, which allows it to deliver more power with lower power losses..

The MIC5318 is also well suited for applications requiring high efficiency and low noise. The MIC5318 uses a low quiescent current of 7mA, which allows it to maintain a high overall efficiency while still maintaining a low noise output. The MIC5318 also has a low output noise of just 0.5mV RMS, which is important in high-performance applications or devices that require low noise power supplies for signal conditioning.

The MIC5318 is available as a 14-pin PDIP or MSOP package, allowing for easy implementation in applications where space is at a premium. It is also available in a compact 3x3mm QFN package for small, portable designs. The MIC5318 is fully protected against thermal events, short-circuits and over-voltage, providing the designer with a solution that is both reliable and safe.

In summary, the MIC5318 is an ideal choice for applications that require low dropout, high efficiency, and high power supply rejection. Its small form factor and low power losses makes it an ideal choice for portable applications. It also provides excellent line and load regulation as well as a low output noise, making it suitable for use in high-performance applications.
