MIC5320-MMYD6

MIC5320-MMYD6 Description

The MIC5320-MMYD6 is a high-performance dual 150 mA linear voltage regulator designed by Micrel Inc. This regulator is engineered to provide stable and efficient power management in a compact form factor. With a fixed output voltage of 2.8V for both regulators, it ensures consistent power delivery to sensitive electronic components. The input voltage range extends up to 5.5V, making it suitable for a variety of applications where input voltage fluctuations are common. The regulator's low dropout voltage of 0.1V at 150mA ensures high efficiency, even at low input-to-output voltage differentials.

MIC5320-MMYD6 Features

• Dual Fixed Output Regulators: The MIC5320-MMYD6 features two independent fixed output regulators, each capable of delivering up to 150mA of current. This dual configuration is ideal for applications requiring separate power supplies for different components.
• Low Dropout Voltage: With a maximum dropout voltage of 0.1V at 150mA, the regulator maintains high efficiency even when the input voltage is close to the output voltage. This feature is particularly beneficial in battery-powered devices where the input voltage may drop significantly over time.
• Low Quiescent Current: The regulator operates with a quiescent current of only 120 µA, contributing to extended battery life in portable applications.
• Enable Control Feature: The enable control feature allows for dynamic control of the regulator's operation, enabling power-saving modes and reducing power consumption when the regulator is not in use.
• Protection Features: The MIC5320-MMYD6 includes over-current and over-temperature protection, ensuring reliable operation and safeguarding against potential damage from short circuits or excessive heat.
• High PSRR: The regulator boasts a high power supply rejection ratio (PSRR) ranging from 65dB to 45dB across frequencies from 1kHz to 20kHz, effectively filtering out noise and ripple from the input voltage.
• Surface Mount Package: The surface mount package type facilitates easy integration into modern printed circuit boards (PCBs) and supports automated assembly processes.

MIC5320-MMYD6 Applications

The MIC5320-MMYD6 is well-suited for a range of applications where dual power supply regulation is required.
