From the project

LTspice and KiCad portfolio project for a sequenced three-rail power-management block.

LTspice and KiCad portfolio project for a sequenced three-rail power-management block.

This project converts a single 5 V input into three sequenced rails for an SoC + sensor cluster:

The design includes input protection, regulator-stage modeling, output capacitance, equivalent loads, enable sequencing, Rail C load-step simulation, KiCad schematic capture, BOM files, and interview/report documentation.
