Additional Details

The MIC5332-2.85/2.85YMT is commonly used to power microcontrollers, memory chips, and other low-power components in portable devices. Its high accuracy and low dropout voltage ensure that the components receive the correct voltage even when the input voltage is close to the output voltage. The device's small size and low power consumption make it an ideal choice for space-constrained and battery-powered applications. The thermal shutdown feature protects the device from overheating under fault conditions.

The use of ceramic capacitors provides stability and reduces the overall solution size and cost. This device is often used in applications that require two separate 2.85V rails, simplifying the power supply design and reducing component count.
