Description

The MCP1825/MCP1825S is a 500 mA Low Dropout(LDO) linear regulator that provides high current andlow output voltages. The MCP1825 comes in a fixed oradjustable output voltage version, with an outputvoltage range of 0.8V to 5.0V. The 500 mA outputcurrent capability, combined with the low output voltagecapability, make the MCP1825 a good choice for newsub-1.8V output voltage LDO applications that havehigh current demands. The MCP1825S is a 3-pin fixedvoltage version.The MCP1825/MCP1825S 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-limitingprovide additional protection for the LDO during systemfault conditions.
