Technical Specifications

The MIC5303-3.3YMT has a fixed output voltage of 3.3V. It typically operates with input voltages between 2.5V and 5.5V. The dropout voltage is very low, typically less than 200mV at the rated output current. The output current is typically up to 200mA. The quiescent current is very low, typically in the microampere range. The device includes current limiting and thermal shutdown protection features. It's packaged in a tiny package such as a Thin QFN package. Check the datasheet for exact values and package details.

The MIC5303-3.3YMT's low dropout voltage allows it to operate efficiently even when the input voltage is close to the output voltage, extending battery life in portable devices. Its high output accuracy ensures stable and reliable power supply for sensitive electronic components. The ultra-small package size makes it ideal for space-constrained applications. The device is also stable with ceramic output capacitors, eliminating the need for bulky tantalum or electrolytic capacitors. The current limiting and thermal shutdown features protect the device and the powered circuitry from damage due to overcurrent and overtemperature conditions.
