The MCP1727 is a 1.5A Low Dropout (LDO) linear
regulator that provides high current and low output
voltages in a very small package. The MCP1727 comes in a fixed (or adjustable) output voltage version, with an output voltage range of 0.8V to 5.0V. The 1.5A output current capability, combined with the low output voltage capability, makes the MCP1727 a good choice
for new sub-1.8V output voltage LDO applications that have high current demands.
The MCP1727 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 MCP1727 is typically less than 120 µA over the entire input voltage range, making it attractive for portable computing applications that
demand high output current. When shut down, the quiescent current is reduced to less than 0.1 µA.
