Pinout
1. Pin 1 (VIN): This is the input voltage pin. The voltage you want to regulate is applied here.
2. Pin 2 (GND): This is the ground pin. It serves as the reference point for the input and output voltages.
3. Pin 3 (Enable/Shutdown - EN): This pin is used to enable or disable the regulator. Pulling it high enables the regulator, while pulling it low puts the regulator in a low-power shutdown mode.
4. Pin 4 (ADJ - Adjust): This is the adjust pin, used to set the output voltage with external resistors.
5. Pin 5 (VOUT): This is the regulated output voltage pin. The output voltage is determined by the voltage divider connected to the ADJ pin.
The MIC49300WR is known for its efficiency in providing a stable output voltage with low dropout and high current capabilities, making it suitable for various power management applications.
