MIC2211-NSYML Description

The MIC2211-NSYML is a dual-channel low dropout linear regulator (LDO) designed for applications requiring high efficiency and minimal power dissipation. Manufactured by Micrel Inc., this device falls under the Power Management (PMIC) category and is ideal for a wide range of electronic systems where space and power efficiency are critical. The MIC2211-NSYML offers two fixed output voltages of 2.85V and 3.3V, with maximum input voltage up to 5.5V. It supports output currents of 150mA and 300mA, making it suitable for both low and moderate power applications.

MIC2211-NSYML Features

Low Quiescent Current: The MIC2211-NSYML boasts a low quiescent current of 80 µA, which is crucial for battery-operated devices where power conservation is essential. This feature ensures minimal power consumption during standby or low-load conditions, extending the operational life of the system.

High PSRR: With a Power Supply Rejection Ratio (PSRR) ranging from 60dB at 1kHz to 40dB at 20kHz, the MIC2211-NSYML effectively filters out noise from the input supply, ensuring clean and stable output voltages. This is particularly beneficial in sensitive analog and digital circuits.

Low Dropout Voltage: The device features a low dropout voltage of 0.25V at 150mA and 0.42V at 300mA. This allows the regulator to maintain regulation even when the input voltage is close to the output voltage, enhancing efficiency and extending the battery life in portable applications.

Dual Regulators: The MIC2211-NSYML includes two independent regulators, providing flexibility in system design. This dual configuration is ideal for applications requiring multiple voltage rails, reducing the need for additional components and saving board space.

Enable Control: The enable feature allows for dynamic control of the regulator's operation, enabling power savings and system flexibility. This is particularly useful in systems that require power sequencing or remote control.

Protection Features: The device incorporates over-current and over-temperature protection, ensuring reliable operation under various operating conditions. These features safeguard the regulator and downstream components from potential damage due to excessive current or temperature.

Surface Mount Packaging: The MIC2211-NSYML is available in a surface mount package, making it suitable for automated assembly processes and compact designs. This packaging option is ideal for modern electronics where space is at a premium.
