What are the key features of MCP1726-5002E/SN?
- 1 A output current with a low 220 mV typical dropout voltage, enabling efficient 5 V regulation from 5.5 V input rails
- Fixed 5.0 V output in a compact 8-pin SOIC package, simplifying PCB layout for space-constrained designs
- CMOS LDO architecture with up to 6.5 V absolute maximum input rating for robust operation in USB and adapter-powered systems
What is MCP1726-5002E/SN used for?
The MCP1726-5002E/SN is suited for post-regulation of 5 V USB power rails and adapter outputs where input voltage sits between 5.5 V and 6 V and a stable 5.0 V output is required. Its 1 A current capability and low 220 mV dropout make it a natural fit for microcontroller supply rails in consumer electronics, IoT gateways, and portable instruments. The 8-pin SOIC footprint also eases migration from other CMOS LDOs in existing board designs.

Frequently Asked Questions
What is the minimum input voltage needed for MCP1726-5002E/SN to maintain its 5.0 V output at 1 A?
At a 1 A load current the MCP1726-5002E/SN requires at minimum approximately 5.22 V input, since its typical dropout voltage is 220 mV and the fixed output is 5.0 V. The specified input voltage operating range starts at 5.5 V, providing additional headroom for line variations and ensuring the 5.0 V rail stays within regulation even during input sag.
How does MCP1726-5002E/SN fit into a USB 5 V bus-powered embedded system design?
In a USB-powered system where the bus supplies 5.0 V to 5.25 V, the MCP1726-5002E/SN can be used after a boost or charge-pump stage that raises the rail to 5.5 V or higher, then regulates it back to a clean 5.0 V with up to 1 A for microcontrollers and peripherals. The 8-pin SOIC footprint keeps the solution compact, and the 220 mV typical dropout minimizes power loss in the conversion stage.
Which competing 1 A 5 V LDO in an 8-pin SOIC should engineers evaluate alongside MCP1726-5002E/SN?
Engineers often compare MCP1726-5002E/SN against parts such as the Microchip MCP1825 series and LP2985 family, all of which deliver fixed 5 V outputs at up to 1 A in similar small packages. The MCP1726 differentiates itself with a 220 mV typical dropout at full load versus higher dropout values found in some alternatives, giving it an edge in 5.5 V to 6 V input scenarios where efficiency matters.
