The MCP1825/MCP1825S is a 500 mA Low Dropout (LDO) linear regulator that provides high current and low output voltages. The MCP1825 comes in a fixed or adjustable output voltage version, with an output voltage range of 0.8 V to 5.0 V. The 500 mA output current capability, combined with the low output voltage capability, make the MCP1825 a good choice for new sub-1.8 V output voltage LDO applications that have high current demands. The MCP1825S is a 3-pin fixed voltage version. Features:
