Description

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, 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 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

140 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.

The scaled-down output voltage is internally monitored

and a power good (PWRGD) output is provided when

the output is within 92% of regulation (typical). An

external capacitor can be used on the C

adjust the delay from 1 ms to 300 ms.

The overtemperature and short circuit current-limiting

provide additional protection for the LDO during system

fault conditions.
