The uP0104 is a linear regulator, meaning it dissipates power as heat. The power dissipation ($P_D$) is calculated as: $$P_D = (V_in - V_out) \times I_load$$ For example, regulating 12V down to 5V at 500mA results in 3.5 Watts of heat dissipation. In such cases, the SOT-223 package alone may be insufficient, and an external heatsink or copper plane on the PCB is required.

Most variants are rated for 500mA to 1A , depending on the specific package and thermal dissipation. : When designing your PCB layout, optimize for
