MCP1726  
1A, Low Voltage, Low Quiescent Current LDO Regulator  
Features  
Description  
• 1A Output Current Capability  
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.  
• Input Operating Voltage Range: 2.3V to 6.0V  
• Adjustable Output Voltage Range: 0.8V to 5.0V  
• Standard Fixed Output Voltages:  
- 0.8V, 1.2V, 1.8V, 2.5V, 3.3V, 5.0V  
• Low Dropout Voltage: 220 mV Typical at 1A  
• Typical Output Voltage Tolerance: 0.4%  
• Stable with 1.0 µF Ceramic Output Capacitor  
• Fast response to Load Transients  
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.  
• Low Supply Current: 140 µA (typ)  
• Low Shutdown Supply Current: 0.1 µA (typ)  
• Adjustable Delay on Power Good Output  
• Short Circuit Current Limiting and  
Overtemperature Protection  
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.  
• 3X3 DFN-8 and SOIC-8 Package Options  
Applications  
• High-Speed Driver Chipset Power  
• Networking Backplane Cards  
• Notebook Computers  
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 CDELAY pin to  
adjust the delay from 1 ms to 300 ms.  
• Network Interface Cards  
• Palmtop Computers  
• 2.5V to 1.XV Regulators  
The overtemperature and short circuit current-limiting  
provide additional protection for the LDO during system  
fault conditions.
