Description
The MCP1726 is a 1A Low Dropout (LDO) linear
regulator that provides high current and low output
voltages in a very small package. The MCP1726
comes in a fixed (or adjustable) output voltage version,
with an output voltage range of 0.8V to 5.0V. The 1A
output current capability, combined with the low output
voltage capability, make 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 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 MCP1726 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.
