MIC5317-2.5YMT-TZ is an ultra low drop-out linear voltage regulator, fabricated on advanced CMOS process technology, that features extremely low quiescent current and high power supply rejection ratio (PSRR). It provides an industry leading low drop out voltage of 0.4V for ksinksidifferent output current. The device comes in a small packaged and is avaliable in fixed output voltage ranges from 0.8V to 6V for available in 3 pin SOT-23, 5 pin SOT-23, 8 pin SOIC, and 8 pin TSSOP packages.

The MIC5317-2.5YMT-TZ linear voltage regulator has a wide variety of applications. It is particularly suitable for use in applications like Notebook Computers, Personal Digital Assistants(PDAs), Cellular Telephones, and other handheld devices requiring low drop-out voltage and enhanced PSRR. The low output impedance makes the device ideal for high current applications, such as secondary cell phone batteries, back-up memory supplies, and high current battery operation.

The MIC5317-2.5YMT-TZ features an input voltage range from 3.0V to 10 V and provides an output voltage range from 0.8V to 6V. The output voltage is adjustable via an external resistor divider to approximately ±1.5% accuracy. The device has a very low quiescent current, typically 0.44mA. The device also features a high PSRR of 70dB and low noise of 30μVrms, ensuring minimum line regulation over the entire operating temperature range.

The MIC5317-2.5YMT-TZ works by controlling the output voltage by comparing the feedback voltage on the FB pin to the internal reference voltage of 0.8V. When the FB voltage exceeds the 0.8V reference voltage, the device starts to reduce the output current to lower the output voltage. When the FB voltage is less than 0.8V, the device will increase the output current to increase the output voltage. This method of output voltage control ensures that the output voltage is accurately regulated over the entire input voltage range. In addition, the device also features over-current protection, over-temperature protection, and short-circuit protection.

The MIC5317-2.5YMT-TZ is an ultra low drop-out linear voltage regulator which provides an industry-leading low drop-out voltage of 0.4V for different output current. The device is designed to provide low quiescent current and high power supply rejection ratio. It is a highly efficient and reliable solution for various applications requiring low quiescent current and high PSRR. The device is also cost effective, making it an attractive choice for designers.
