Additional Details:

The MIC5213-2.5YC5 is available in a SOT-23-5 package. It operates from an input voltage range typically between 2.5V and 5.5V. It provides a fixed 2.5V output voltage and is capable of delivering a maximum output current of 500mA. The low dropout voltage allows it to maintain regulation even when the input voltage is close to the output voltage.

The device also features an enable pin, allowing for shutdown mode, further reducing power consumption when the regulator is not needed.
