MCP1710  
Ultra-Low Quiescent Current LDO Regulator  
Features  
Description  
• Ultra-Low 20 nA (typical) Quiescent Current  
The MCP1710 is a 200 mA for VOUT < 3.5V, 100 mA for  
VOUT > 3.5V, low dropout (LDO) linear regulator that  
provides high-current and low-output voltages, while  
maintaining an ultra-low 20 nA of quiescent current  
during device operation. In addition, the MCP1710 can  
be shut down for an even lower 0.1 nA (typical) supply  
current draw. The MCP1710 comes in five standard  
fixed output voltage versions: 1.2V, 1.8V, 2.5V, 3.3V  
and 4.2V. The 200 mA output current capability,  
combined with the low output-voltage capability, make  
the MCP1710 a good choice for new ultra-long-life LDO  
applications that have high current demands, but  
require ultra-low power consumption during sleep  
states.  
• Ultra-Low Shutdown Supply Current:  
0.1 nA (typical)  
• 200 mA Output Current Capability for  
V
OUT < 3.5V  
• 100 mA Output Current Capability for  
OUT > 3.5V  
V
• Input Operating Voltage Range: 2.7V to 5.5V  
• Standard Output Voltages:  
- 1.2V, 1.8V, 2.5V, 3.3V, 4.2V  
• Low-Dropout Voltage: 450 mV Maximum at  
200 mA  
• Stable with 1.0 µF Ceramic Output Capacitor  
• Overcurrent Protection  
The MCP1710 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 (2.2 µF recommended) of output  
capacitance is needed to stabilize the LDO.  
• Space Saving, 8-Lead Plastic 2 x 2 VDFN-8  
Applications  
• Energy harvesting  
The MCP1710’s ultra-low quiescent and shutdown  
current allows it to be paired with other ultra-low current  
draw devices, such as Microchip’s nanoWatt XLP  
technology devices, for a complete ultra-low power  
solution.  
• Long-life battery powered applications  
• Smart cards  
• Ultra-Low consumption “Green” products  
• Portable electronics
