... Description The MCP1826/MCP1826S is a 1000 mA Low Dropout (LDO) linear regulator that provides high current and low output voltages. The MCP1826 comes in a fixed or adjustable output voltage version, with an output voltage range of 0.8V to 5.0V. The 1000 mA output cur- rent capability, combined with the low output voltage capability, make the MCP1826 a good choice for new sub-1 ...

... I VIN PWRGD The total power dissipated within the MCP1826/ MCP1826S is the sum of the power dissipated in the LDO pass device and the P(I CMOS construction, the typical I MCP1826S 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 ...

... MCP1826/MCP1826S The maximum power dissipation capability for a package can be calculated given the junction-to- ambient thermal resistance and the maximum ambient temperature for the application.
