development onto smaller geometries, requiring separate
voltages for the core and I/O. The MCP1726 meets
these requirements with high output current and low
core voltage, making it an ideal solution for the growing
number of applications using high-performance general-
purpose embedded processors and next-generation logic
cores. These applications include:
? Computers (PC motherboards, PC add-in cards
and graphics processor cards)
? Consumer (high-end digital set top boxes, high-end
television sets and LCD projection devices)
? Industry/power supplies (SMPS post regulators and
automated control systems)
The MCP1726 LDO features output voltage down to 0.8V
at 1 amp output current, supporting next-generation high-
performance CPUs and logic cores. The output voltage
setting can be adjusted from 0.8V to 5.0V using two
external resistors, or set to a predetermined fixed value
such as 0.8V, 1.2V, 1.8V, 2.5V, 3.3V and 5.0V.
The MCP1726 monitors its output voltage internally and
provides Power Good output when the output is within
92% of regulation. An external capacitor can be used on
the Cdelay pin to adjust the delay from 1 μs to 300 μs. The
typical default delay is 200 μs. Using CMOS construction,
the internal quiescent current of the MCP1726 is typically
Key Features of the MCP1726
? Up to 1A output load current
? Power Good output with adjustable delay
? Stable with 1.0 μF ceramic output cap
? Over-current and over-temperature protection/thermal
shutdown
? A 140 microamp maximum ground current for optimum
energy ef?ciency
? A small, 8-pin DFN package for space-constrained
applications
? Shutdown and/or Reset options
? Fold-back output current limit
? Supported temperature range of -40 ° C to +125 ° C.
? Low dropout voltage of 150 mV @ 1A typical
? Fast response to load and line transients
less than 140 μA. When the LDO is shut down, the
quiescent current is less than 0.1 μA.
The LDO is stable with a 1 microfarad ceramic output
capacitor, reducing cost and board space. The power
good output with programmable delay option allows
engineers to program a system delay on a wider time
frame, providing additional ?exibility for the design and
reducing customer inventory.
