Description

The MCP1826/MCP1826S is a 1000 mA Low Dropout(LDO) linear regulator that provides high-current andlow-output voltages. The MCP1826 comes in a fixed oradjustable output voltage version, with an outputvoltage range of 0.8V to 5.0V. The 1000 mA output current capability, combined with the low-output voltagecapability, make the MCP1826 a good choice for newsub-1.8V output voltage LDO applications that havehigh current demands. The MCP1826S is a 3-pin fixedvoltage version.The MCP1826/MCP1826S is stable using ceramicoutput capacitors that inherently provide lower outputnoise and reduce the size and cost of the entireregulator solution. Only 1 µF of output capacitance isneeded to stabilize the LDO. The overtemperature and short circuit current-limiting provide additional protection for the LDO during system Fault conditions.
