Hi ananthuv10,

Thanks for posting your query.

3.3V Low-Drop Buck Voltage Regulator supports up to 500mA of output current. For higher operating temp i.e. 125Deg, it is safe to draw up to 300mA based on cooling area provided on the PCB.

5V Low-Drop Linear Voltage Regulator supports up to 100mA.

For thermal calculations kindly refer to the 2nd chapter of the below-mentioned user guide.

kindly feel free to ask if you need any other support or information.

Thanks & Regards,
