Description The MCP1825/MCP1825S is a 500 m A Low Dropout (LDO) linear regulator that provides high current and low output voltages. The MCP1825 es in a fixed or adjustable output voltage version, with an output voltage range of 0.8V to 5.0V. The 500 m A output current capability, bined with the low output voltage capability, make the MCP1825 a good choice for new sub-1.8V output voltage LDO applications that have high current demands. The MCP1825S is a 3-pin fixed voltage version. The MCP1825/MCP1825S is stable using ceramic output capacitors that inherently provide lower output noise and reduce the size and cost of the entire regulator solution. Only 1 µF of output capacitance is needed to stabilize the LDO. Using CMOS construction, the quiescent current consumed by the MCP1825/MCP1825S is typically less than 120 µA over the entire input voltage range, making it attractive for portable puting applications that demand high output current. The MCP1825 versions have a Shutdown (SHDN) pin. When shut down, the quiescent current is reduced to less than 0.1 µA. On the...
