... I VIN PWRGD The total power dissipated within the MCP1825/ MCP1825S is the sum of the power dissipated in the LDO pass device and the P(I CMOS construction, the typical I MCP1825S is 120 µA. Operating at a maximum V 3.465V results in a power dissipation of 0.12 milli-Watts for a 2.5V output. For most applications, this is small compared to the LDO pass device power dissipation and can be neglected ...
