Frequently Asked Questions
How low can the input voltage of MCP1700-1202E/TO drop before it loses regulation at 250 mA?
MCP1700-1202E/TO has a typical dropout voltage of 0.15 V and a maximum of 0.35 V, meaning the input must stay at least 0.35 V above the 1.2 V output. At a 250 mA load, the input can drop to approximately 1.55 V before dropout occurs, extending usable battery life significantly in low-voltage designs.
Is MCP1700-1202E/TO a good fit for a 2-cell AA battery-powered sensor node running at 1.2 V?
Yes. MCP1700-1202E/TO accepts input voltages from 2.3 V to 6 V, which covers the discharge range of 2 AA alkaline cells. The 0.15 V typical dropout allows the regulator to maintain the 1.2 V output rail until the battery pack falls to approximately 1.55 V, maximizing energy extraction from each cell pair.
What is the procurement lead time for MCP1700-1202E/TO and how should buyers plan inventory?
Factory lead time for MCP1700-1202E/TO is approximately 24 weeks, which is notably longer than typical LDO regulators. Production planners should carry a minimum of 6-month safety stock or qualify a pin-compatible fixed 1.2 V LDO with similar 250 mA rating and TO-92 package to hedge against supply disruptions.
How does the TO-92 package of MCP1700-1202E/TO affect board assembly in low-cost consumer designs?
The 3-pin TO-92 package requires only 3 through-holes at standard 1.27 mm spacing, making it compatible with hand-soldering, wave soldering, and simple jig-based assembly. This reduces manufacturing cost in high-volume consumer products compared to SOT-23 SMT alternatives that require reflow equipment and finer placement tolerances.
