MCP1725  
500 mA, Low Voltage, Low Quiescent Current LDO Regulator  
Features  
Description  
• 500 mA Output Current Capability  
The MCP1725 is a 500 mA Low Dropout (LDO) linear  
regulator that provides high current and low output  
voltages in a very small package. The MCP1725  
comes in a fixed (or adjustable) output voltage version,  
with an output voltage range of 0.8V to 5.0V. The  
500 mA output current capability, combined with the  
low output voltage capability, make the MCP1725 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, 3.0V, 3.3V, 5.0V  
• Other Fixed Output Voltage Options Available  
Upon Request  
• Low Dropout Voltage: 210 mV Typical at 500 mA  
• Typical Output Voltage Tolerance: 0.5%  
• Stable with 1.0 µF Ceramic Output Capacitor  
• Fast response to Load Transients  
The MCP1725 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: 120 µA (typ)  
• Low Shutdown Supply Current: 0.1 µA (typ)  
• Adjustable Delay on Power Good Output  
Using CMOS construction, the quiescent current  
consumed by the MCP1725 is typically less than  
120 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.  
• Short Circuit Current Limiting and  
Overtemperature Protection  
• 2x3 DFN-8 and SOIC-8 Package Options  
Applications  
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 200 µs to 300 ms.  
• High-Speed Driver Chipset Power  
• Networking Backplane Cards  
• Notebook Computers  
• Network Interface Cards  
• Palmtop Computers  
The overtemperature and short circuit current-limiting  
provide additional protection for the LDO during system  
fault conditions.  
• Video Graphics Adapters  
• 2.5V to 1.XV Regulators
