MIC2211-NNYML

MIC2211-NNYML Description

The MIC2211-NNYML is a dual linear low-dropout (LDO) voltage regulator designed for high-performance power management applications. Manufactured by Micrel Inc., this IC offers a compact and efficient solution for providing stable power to sensitive electronic circuits. The device features a quiescent current of only 80 µA, ensuring minimal power consumption even during idle states. It supports a maximum input voltage of 5.5V and provides two fixed output voltages of 2.85V, each capable of delivering up to 150mA and 300mA respectively. The regulator's dropout voltage is impressively low, at a maximum of 0.25V for 150mA and 0.42V for 300mA, which allows it to maintain regulation even when the input-to-output voltage differential is small.

MIC2211-NNYML Features

The MIC2211-NNYML stands out due to its combination of high performance and robust protection features. It boasts a power supply rejection ratio (PSRR) that ranges from 60dB at 1kHz to 40dB at 20kHz, effectively filtering out noise from the input supply and ensuring clean output voltage. The regulator is equipped with enable control, allowing users to turn the regulator on or off as needed, which is particularly useful for power-saving applications. Additionally, the device includes over-current and over-temperature protection, safeguarding both the regulator and the connected circuitry from damage.

The MIC2211-NNYML is designed for surface-mount applications, making it suitable for modern, space-constrained designs. Its positive output configuration and fixed output voltage simplify the design process, reducing the need for additional components. The device is available in bulk packaging, which is ideal for high-volume production runs. With an ECCN classification of EAR99 and an HTSUS code of 8542.39.0001, the MIC2211-NNYML complies with international export regulations and customs requirements.
