Frequently Asked Questions
How low can the input voltage drop before MCP1726-1202E/SN loses regulation at full 1 A load?
At a 1 A load, MCP1726-1202E/SN has a typical dropout voltage of 0.22 V, so the input must remain above approximately 1.42 V (1.2 V output plus 0.22 V dropout) to maintain regulation, with the absolute minimum input voltage rating of 1.7 V defining the safe operating floor.
What does the power-good output on MCP1726-1202E/SN enable in a multi-rail power sequencing design?
The open-drain power-good (PG) pin asserts high once the 1.2 V output is within regulation, allowing downstream rails or microcontrollers to be enabled in a controlled sequence. This prevents brown-out conditions in systems where a processor core must power up before its I/O rail.
Can MCP1726-1202E/SN be directly powered from a single-cell Li-ion battery across the full discharge curve?
A single-cell Li-ion battery discharges from approximately 4.2 V down to about 3.0 V, which comfortably spans the 1.7 V to 6 V input range of MCP1726-1202E/SN. The low 0.22 V dropout ensures the 1.2 V output remains stable until the cell is nearly fully discharged.
What PCB footprint is needed and what lead-time should procurement plan for this part?
MCP1726-1202E/SN uses a standard SOIC-8 footprint with 8 pins on 1.27 mm pitch, which is supported by virtually all SMT assembly lines. Typical factory lead time is around 6 weeks, so procurement should maintain adequate safety stock for production schedules.
