MCP1726-ADJE/MF

The MCP1726-ADJE/MF is a low-voltage low quiescent current low-dropout (LDO) Linear Regulator provides high current and low output voltages. The 1A output current capability and low output voltage capability makes the MCP1726 a good choice for new sub-1.8V output voltage LDO applications that have high current demands. The MCP1726 is stable using ceramic output capacitors that inherently provide lower output noise and reduce the size 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 MCP1726 is typically less than 140µA over the entire input voltage range, making it attractive for portable computing applications that demand high output current. When the MCP1726 is shut down, the quiescent current is reduced to less than 0.1µA. The scaled-down output voltage is internally monitored and a power good output is provided when the output is within 92% of regulation.
