Given the information available and the absence of datasheet excerpts for IC1 (TPS62040DGQ) and U4 (LM36011YKBR), I will provide a comparison based on general knowledge and the provided excerpt for U3 (MCP1700T-3302E/TT). Please note that for IC1 and U4, you may need to refer directly to their datasheets for precise and detailed specifications.

Given that detailed datasheets for the STM32L476ZGT6P (U1) and STM32L4R7AII6 (U2) microcontrollers are not directly provided here, I will base the comparison on typical characteristics for STM32L4 series MCUs, acknowledging that while many features and electrical specifications will be similar across the series, specific details can vary between model numbers. Please consult the actual datasheets for the most accurate and detailed information.
