MCP1825/MCP1825S  
500 mA, Low Voltage, Low Quiescent Current LDO Regulator  
Features  
Description  
• 500 mA Output Current Capability  
The MCP1825/MCP1825S is a 500 mA Low Dropout  
(LDO) linear regulator that provides high current and  
low output voltages. The MCP1825 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 MCP1825 a good choice for new  
sub-1.8V output voltage LDO applications that have  
high current demands. The MCP1825S is a 3-pin fixed  
voltage version.  
• Input Operating Voltage Range: 2.1V to 6.0V  
• Adjustable Output Voltage Range: 0.8V to 5.0V  
(MCP1825 only)  
• 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 MCP1825/MCP1825S 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 (typical)  
• Low Shutdown Supply Current: 0.1 µA (typical)  
(MCP1825 only)  
Using CMOS construction, the quiescent current  
consumed by the MCP1825/MCP1825S is typically  
less than 120 µA over the entire input voltage range,  
making it attractive for portable computing applications  
that demand high output current. The MCP1825  
versions have a Shutdown (SHDN) pin. When shut  
down, the quiescent current is reduced to less than  
0.1 µA.  
• Fixed Delay on Power Good Output  
(MCP1825 only)  
• Short Circuit Current Limiting and  
Overtemperature Protection  
• TO-263-5 (DDPAK-5), TO-220-5, SOT-223-5  
Package Options (MCP1825).  
• TO-263-3 (DDPAK-3), TO-220-3, SOT-223-3  
Package Options (MCP1825S).  
On the MCP1825 fixed output versions, 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). The  
PWRGD delay is internally fixed at 110 µs (typical).  
Applications  
• High-Speed Driver Chipset Power  
• Networking Backplane Cards  
• Notebook Computers  
The overtemperature and short circuit current-limiting  
provide additional protection for the LDO during system  
fault conditions.  
• Network Interface Cards  
• Palmtop Computers  
• 2.5V to 1.XV Regulators
