What is MCP1700T-1202E/TT used for?
The MCP1700T-1202E/TT is used in battery-powered portable devices, IoT sensor nodes, and wearable electronics where a compact 1.2 V regulated supply at up to 250 mA is needed from a single-cell Li-ion or AAA battery. Its ultra-low dropout of 0.15 V typical allows it to supply low-voltage FPGAs and DDR memory cores efficiently near the end of battery discharge. It also serves as a local post-regulator for noise-sensitive analog circuits and low-voltage digital logic in space-constrained PCB designs.

Frequently Asked Questions
How low can the input voltage drop before MCP1700T-1202E/TT loses regulation at 1.2 V output?
The MCP1700T-1202E/TT has a typical dropout of 0.15 V and a maximum of 0.35 V, so it maintains a regulated 1.2 V output as long as the input stays above approximately 1.35 V to 1.55 V, extending usable battery life in single-cell Li-ion and NiMH-powered devices.
Can MCP1700T-1202E/TT power a low-voltage FPGA core from a 3.3 V supply rail?
Yes. With a 3.3 V input well within its 6 V maximum, the MCP1700T-1202E/TT easily delivers a regulated 1.2 V at up to 250 mA to power FPGA core voltage rails, memory, or low-voltage logic requiring a stable sub-1.5 V supply.
What makes the 3-pin SOT-23 package of MCP1700T-1202E/TT suitable for wearable and IoT PCB designs?
The SOT-23-3 package occupies less than 2 mm x 1.25 mm of PCB area, making it one of the smallest LDO footprints available. Combined with the fixed output that eliminates external resistors, MCP1700T-1202E/TT achieves a minimal 2-3 component power supply block ideal for ultra-compact IoT and wearable boards.
What is the lead time and compliance status of MCP1700T-1202E/TT for production sourcing?
MCP1700T-1202E/TT has a factory lead time of 5 weeks and is both REACH-compliant and lead-free (Pbfree: Yes), supporting RoHS-mandated assembly processes. Procurement teams should plan buffer stock for a 5-week replenishment cycle when sourcing for ongoing production.
