Voltage limiter with ic source


inrush current protector to protect capacitor from fast charging and let mosfets work as soft start + polarity protection in the same schematic


charge pump circuit or bootstrap (diodes + capacitors+ pwm signal)




some ics need minimum output current or continious conduction mode



multi sources diodes

hystarisis comparator

put capacitors with voltage divider

voltage regulator ic vs voltage reference ic


before any ic source we put capacitors for decobling and some times we need more than one parallel capacitor for lower esr and more smoothing
