Frequently Asked Questions

What is the maximum input voltage the MCP1703AT-1502E/CB can handle, and does it suit 12 V automotive power rails?

The MCP1703AT-1502E/CB accepts input voltages up to 16 V continuously, with a transient absolute maximum of 18 V. A 12 V automotive rail falls well within this range, making it suitable for producing a stable 1.5 V output for sensors or microcontrollers in automotive accessory designs, provided the 1.2 V dropout voltage is respected.

How does the 1.2 V dropout voltage of MCP1703AT-1502E/CB affect its usable input voltage range at a 1.5 V output?

With a 1.5 V fixed output and a 1.2 V typical dropout, the MCP1703AT-1502E/CB requires at least 2.7 V input to maintain regulation. This means it cannot be used directly from a discharged lithium-ion cell below 2.7 V, but remains functional across most alkaline-battery, USB, and regulated DC rail conditions from 2.7 V to 16 V.

Is the MCP1703AT-1502E/CB suitable for a 3-pin SOT-23 PCB footprint already designed for a competing LDO, and is it RoHS-compliant?

Yes. The MCP1703AT-1502E/CB uses a 3-pin SOT-23A package, which is footprint-compatible with many industry-standard 3-pin LDOs in the SOT-23 family. It also carries a JESD-609 code of e3, confirming RoHS-compliant, lead-free construction for designs governed by EU RoHS or similar environmental directives.
