MIC5310-MFYML

MIC5310-MFYML Description

The MIC5310-MFYML is a dual linear low-dropout regulator (LDO) designed for high performance and efficiency in power management applications. Manufactured by Micrel Inc., this IC offers a fixed output voltage configuration with two independent regulators, each capable of delivering up to 150mA of output current. The device is optimized for low quiescent current, drawing only 120 µA, and features a maximum input voltage of 5.5V. With a dropout voltage of just 0.1V at 150mA, the MIC5310-MFYML ensures efficient power delivery even under low input-to-output voltage differentials. The regulator also includes protection features such as over-current and over-temperature protection, enhancing its reliability and robustness. The MIC5310-MFYML is available in a surface-mount package, making it suitable for compact and space-constrained designs.
