It's built for through-hole assembly in the TO-92-3 package, with a maximum dropout voltage of 0.6V at full load — enough headroom for a 5V rail to regulate cleanly down to 3.3V. ## Dropout and quiescent current — sizing the rail At 100 mA output the dropout is 0.6V max, so the input must stay above 3.9V to maintain regulation. Quiescent current is 120 µA typical, rising to 14 mA max under fault — the part includes over-current and over-temperature protection, so the supply budget should cover that peak. Input voltage can go up to 30V, which gives plenty of margin for a 12V or 24V industrial bus. The fixed 3.3V output means no external resistor divider — just the input cap and an output cap per the datasheet recommendation. ## Obsolete — sourcing for repair and last-time buy This part is listed as obsolete.","metaTitle":"LP2950CZ-3.3/LFT1 LDO Regulator, 3.3V Fixed, 100mA, TO-92-3","metaDescription":"Obsolete LP2950CZ-3.3/LFT1 fixed 3.3V LDO, 100mA output, 0.6V dropout, -40°C to 125°C.
