MIC5335-OGYMT Description

The MIC5335-OGYMT is a dual, high-performance 300mA low dropout linear regulator designed by Micrel Inc., a leading manufacturer of advanced power management solutions. This device is part of the Power Management Integrated Circuit (PMIC) category and is engineered to provide reliable and efficient power regulation in a wide range of electronic applications. The MIC5335-OGYMT features a fixed output configuration with two independent regulators, each capable of delivering up to 300mA of current. The input voltage range extends up to 5.5V, making it suitable for various power sources. The regulator's low dropout voltage of 0.2V at 300mA ensures high efficiency even under low input-to-output voltage differentials.

MIC5335-OGYMT Features

• Dual Regulators: The MIC5335-OGYMT includes two fixed-output regulators, each with a maximum output current of 300mA. This dual-regulator design allows for simultaneous power management of multiple circuits or components within a single device.
• Low Dropout Voltage: With a dropout voltage of only 0.2V at 300mA, the regulator maintains high efficiency even when the input voltage is close to the output voltage. This feature is particularly beneficial in battery-powered applications where the input voltage may drop as the battery discharges.
• Low Quiescent Current: The regulator operates with a quiescent current of just 125 µA, minimizing power consumption during operation. This low quiescent current is crucial for extending battery life in portable devices.
• High PSRR: The Power Supply Rejection Ratio (PSRR) ranges from 65dB to 45dB across frequencies from 1kHz to 20kHz. This high PSRR ensures that the regulator can effectively filter out noise and ripple from the input power supply, resulting in a cleaner output voltage.
• Enable Control Feature: The regulator includes an enable control feature, allowing users to turn the regulator on or off as needed. This feature enhances power management flexibility and can be used to conserve power during standby or sleep modes.
• Protection Features: The MIC5335-OGYMT incorporates over-current and over-temperature protection mechanisms to safeguard the device and connected circuits from potential damage. These protection features enhance the reliability and robustness of the regulator in various operating conditions.
• Surface Mount Package: The regulator is available in a surface mount package, making it suitable for automated assembly processes and compact electronic designs. The moisture sensitivity level (MSL) of 3 (168 Hours) ensures the device's reliability in different environmental conditions.
