At 100 mA output, this part is sized for low-current loads: a small MCU, a few op-amps, or an isolated sensor supply. Exceed that and the regulator drops out of regulation or hits thermal shutdown. The 62 dB PSRR at 120 Hz tells you how well the part rejects ripple from a full-wave rectified mains supply — useful when the input comes from a transformer-and-capacitor front end rather than a switching preregulator. Quiescent current sits at 3 mA, which is modest for a linear regulator but worth noting in battery-powered designs where every millamp counts. Over-temperature and short-circuit protection are built in, so the part survives a momentary output short without damage. ## Temperature grade and environment Rated for 0°C to 125°C operating junction temperature, this part covers commercial and most industrial indoor environments. ## Lifecycle and sourcing posture That means no last-time-buy pressure and no forced redesign for a replacement. ROHS3 compliant, so it clears the RoHS directive without exemption paperwork. For a BOM freeze, this part is a stable line item; no PCN watch needed unless the fab moves.","metaTitle":"LM78L05ACZ/LFT3 Linear Regulator, 5V Fixed, 100mA, TO-92-3","metaDescription":"LM78L05ACZ/LFT3 5V fixed linear regulator, 100mA output, 62dB PSRR at 120Hz, TO-92-3 package, active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"62dB (120Hz)","Package":"Tape & Box (TB); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA) Formed Leads","lifecycle_stage":"eol_hot","Current - Output":"100mA","Protection Features":"Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"0°C ~ 125°C","Voltage - Input (Max)":"35V","Supplier Device Package":"TO-92-3","Current - Quiescent (Iq)":"3 mA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.92000","currency":"USD"},{"qty":10,"price":"$0.81200","currency":"USD"},{"qty":25,"price":"$0.76240","currency":"USD"},{"qty":100,"price":"$0.62220","currency":"USD"},{"qty":250,"price":"$0.57792","currency":"USD"},{"qty":500,"price":"$0.49184","currency":"USD"},{"qty":1000,"price":"$0.39347","currency":"USD"},{"qty":2000,"price":"$0.35659","currency":"USD"},{"qty":6000,"price":"$0.34800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1147efc7126124802408be8b8d7c58e3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM78L05ACZ/LFT3 compatible with standard LM78L05?","answer":"Yes, the LM78L05ACZ/LFT3 is a standard 78L05 fixed 5 V regulator in a TO-92-3 package.
