MIC5311-GMYML Description

The MIC5311-GMYML is a high-performance, dual low-dropout linear regulator designed by Micrel Inc. for applications requiring efficient power management. This device is part of the Power Management Integrated Circuit (PMIC) category and is specifically tailored for systems that demand low quiescent current and high PSRR (Power Supply Rejection Ratio) to ensure stable and reliable power delivery. The MIC5311-GMYML features a quiescent current of only 50 µA, making it ideal for battery-operated devices and other applications where power efficiency is critical.

MIC5311-GMYML Features

• Low Quiescent Current: With a quiescent current of just 50 µA, the MIC5311-GMYML significantly reduces power consumption, extending battery life in portable devices.
• High PSRR: The regulator offers a PSRR of 65dB at 1kHz, which reduces to 35dB at 20kHz. This high PSRR ensures minimal noise and ripple on the output voltage, providing clean power to sensitive analog and digital circuits.
• Fixed Output Voltage: The MIC5311-GMYML provides two fixed output voltages of 1.8V and 2.8V, eliminating the need for external resistors and simplifying design.
• High Current Capability: Each regulator can deliver up to 300mA of output current, making it suitable for a wide range of applications that require moderate to high current.
• Low Dropout Voltage: The maximum dropout voltage is 0.24V at 300mA, ensuring efficient operation even when the input voltage is close to the output voltage.
• Enable Control: The enable feature allows for dynamic power control, enabling the regulator to be turned on and off as needed, further conserving power.
• Protection Features: Over-current and over-temperature protection ensure the device operates safely under various conditions, enhancing reliability and longevity.
• Surface Mount Packaging: The surface mount technology (SMT) allows for compact and robust PCB designs, suitable for modern electronics manufacturing processes.
• Active Product Status: The MIC5311-GMYML is an active product, ensuring availability and support for ongoing projects.
