Additional Details

The MIC5376-2.8YMT typically operates with an input voltage range of 2.5V to 5.5V. The dropout voltage is typically around 150mV at the rated output current. The quiescent current is typically less than 50µA. It incorporates thermal shutdown protection to prevent damage from overheating. The package type is typically a small, surface-mount package such as a Thin MLF (Micro Lead Frame) package. The regulator requires only a few external components, such as input and output capacitors, to operate. The combination of low power consumption, high accuracy, and robust protection features makes it a popular choice for powering sensitive electronic components in portable devices and other battery-powered applications.
