Additional Details

The MIC5366-2.8YMT TR operates with a wide input voltage range, typically from 2.5V to 5.5V. The output current is typically rated at 300mA. The device is designed to be stable with small ceramic output capacitors, which helps to reduce the overall solution size and cost. The current limit protection prevents damage to the regulator and the load in the event of a short circuit. The thermal shutdown protection disables the regulator when the junction temperature exceeds a safe level.
