MCP1727-ADJE/MF

The MCP1727-ADJE/MF is a low-dropout (LDO) Linear Regulator that provides high current and low output voltages. The MCP1727 comes in an adjustable output voltage version with an output voltage range of 0.8 to 5.0V. The 1.5A output current capability, combined with the low output voltage capability, make 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 1µF of output capacitance is needed to stabilize the LDO. Using CMOS construction, the quiescent current consumed by the MCP1727 is typically less than 120µA 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 0.1µA.
