Key Features
- 1.5 A output current capability in CMOS LDO architecture supporting high-current loads with minimal quiescent power drain
- Low 0.33 V typical dropout voltage (0.55 V max) minimizing headroom requirement to just 675 mV above the 5 V output
- Fixed 5.0 V output voltage with tight regulation for powering 5 V digital logic, sensors, and communication interfaces
- SOIC-8 surface-mount package enabling compact PCB placement with standard automated assembly processes
Applications
MCP1727-5002E/SN is suited for powering 5 V digital logic circuits, USB-powered devices, and microcontroller systems that require a stable high-current 5 V supply from a 6 V input. Its 1.5 A current rating makes it appropriate for powering multiple peripheral devices simultaneously, such as sensors, displays, and communication modules in embedded systems. The low dropout voltage is particularly valuable in battery-backed systems and USB hub applications where the input voltage is only marginally above 5 V.

Frequently Asked Questions
What is the minimum input voltage needed for MCP1727-5002E/SN to maintain full 1.5 A output at 5 V?
MCP1727-5002E/SN requires a minimum input voltage of 5.675 V to start up and maintain regulation. With a maximum dropout voltage of 0.55 V and a 5 V output, the regulator needs at least 5.55 V for rated 1.5 A operation, though the datasheet specifies 5.675 V as the operating minimum input. This narrow input range makes it best suited for precisely regulated 6 V input supplies rather than variable battery inputs.
How does MCP1727-5002E/SN's CMOS architecture affect quiescent current compared to bipolar LDOs at 1.5 A rating?
The CMOS architecture of MCP1727-5002E/SN results in significantly lower quiescent current compared to bipolar LDO regulators of similar current ratings. CMOS LDOs typically achieve quiescent currents below 100 µA, while bipolar designs at 1.5 A can exceed 1 mA. This difference matters in always-on systems where standby efficiency is critical, since the CMOS design reduces idle power dissipation by 5 mW to 10 mW at a 5 V output rail.
Can MCP1727-5002E/SN replace a 7805 linear regulator in existing designs requiring 5 V at 1 A?
MCP1727-5002E/SN can replace a 7805 in designs where 1 A is sufficient — it is rated for 1.5 A and drops out at only 0.55 V maximum versus the 7805's 2 V dropout. The critical difference is input voltage: MCP1727-5002E/SN requires only 5.675 V minimum input compared to the 7805's 7 V minimum, reducing power dissipation. However, MCP1727-5002E/SN uses SOIC-8 SMD packaging versus the 7805's through-hole TO-220, requiring PCB layout changes.
What lead time and packaging options are available when ordering MCP1727-5002E/SN for production quantities?
The factory lead time for MCP1727-5002E/SN is 6 weeks from Microchip's authorized distributors. The '/SN' suffix denotes the standard SOIC-8 tube packaging, while a tape-and-reel option (typically '/SNT' suffix) is available for automated SMT assembly lines with standard 2,500-unit reels. For production orders above 1,000 units, pre-ordering through distribution with the 6-week lead time ensures supply continuity for high-volume manufacturing schedules.
