MCP1826/MCP1826S  
1000 mA, Low Voltage, Low Quiescent Current  
LDO Regulator  
Features  
Description  
• 1000 mA Output Current Capability  
The MCP1826/MCP1826S is a 1000 mA Low Dropout  
(LDO) linear regulator that provides high current and  
low output voltages. The MCP1826 comes in a fixed or  
adjustable output voltage version, with an output  
voltage range of 0.8V to 5.0V. The 1000 mA output cur-  
rent capability, combined with the low output voltage  
capability, make the MCP1826 a good choice for new  
sub-1.8V output voltage LDO applications that have  
high current demands. The MCP1826S is a 3-pin fixed  
voltage version.  
• Input Operating Voltage Range: 2.3V to 6.0V  
• Adjustable Output Voltage Range: 0.8V to 5.0V  
(MCP1826 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: 250 mV Typical at 1000 mA  
• Typical Output Voltage Tolerance: 0.5%  
• Stable with 1.0 µF Ceramic Output Capacitor  
• Fast response to Load Transients  
The MCP1826/MCP1826S 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)  
(MCP1826 only)  
Using CMOS construction, the quiescent current  
consumed by the MCP1826/MCP1826S 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 MCP1826  
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  
(MCP1826 only)  
• Short Circuit Current Limiting and  
Overtemperature Protection  
• TO-263-5 (DDPAK-5), TO-220-5, SOT-223-5  
Package Options (MCP1826).  
• TO-263-3 (DDPAK-3), TO-220-3, SOT-223-3  
Package Options (MCP1826S).  
On the MCP1826 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 200 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
