Microchip continues to expand its portfolio of Low Dropout
Regulators (LDOs) with its new MCP1726 ceramic output
cap stable, low output voltage regulator.
The MCP1726 is the only 1-amp LDO, stable with ceramic
capacitors that incorporates low output voltage, Power
Good and user-programmable Power Good delay on-chip,
providing an ideal solution for a variety of high-performance
system applications.
An Innovative Design
Technology innovation continues to drive microprocessor
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
• Consumer (high-end digital set top boxes, high-end
• Industry/power supplies (SMPS post regulators and
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
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 fl exibility for the design and
reducing customer inventory.
