MCP1827/MCP1827S  
1.5A, Low Voltage, Low Quiescent Current LDO Regulator  
Features  
Description  
• 1.5A Output Current Capability  
The MCP1827/MCP1827S is a 1.5A Low Dropout  
(LDO) linear regulator that provides high current and  
low output voltages. The MCP1827 comes in a fixed or  
adjustable output voltage version, with an output  
voltage range of 0.8V to 5.0V. The 1.5A output current  
capability, combined with the low output voltage  
capability, make the MCP1827 a good choice for new  
sub-1.8V output voltage LDO applications that have  
high current demands. The MCP1827S is a 3-pin fixed  
voltage version. The MCP1827/MCP1827S is based  
upon the MCP1727 LDO device.  
• Input Operating Voltage Range: 2.3V to 6.0V  
• Adjustable Output Voltage Range: 0.8V to 5.0V  
(MCP1827 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: 330 mV Typical at 1.5A  
• Typical Output Voltage Tolerance: 0.5%  
• Stable with 1.0 µF Ceramic Output Capacitor  
• Fast response to Load Transients  
The MCP1827/MCP1827S 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)  
(MCP1827 only)  
Using CMOS construction, the quiescent current  
consumed by the MCP1827/MCP1827S 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 MCP1827  
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  
(MCP1827 only)  
• Short Circuit Current Limiting and  
Overtemperature Protection  
• 5-Lead Plastic DDPAK, 5-Lead TO-220 Package  
Options (MCP1827)  
• 3-Lead Plastic DDPAK, 3-Lead TO-220 Package  
Options (MCP1827S)  
On the MCP1827 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
