It delivers up to 1.5 A of output current and accepts an input voltage up to 35 V. The 68 dB PSRR at 120 Hz means it attenuates full-wave-rectified ripple by a factor of roughly 2500 — useful for cleaning up a bulk capacitor rail before feeding sensitive analog loads. Built-in over-temperature and short-circuit protection let it survive a sustained output short without external crowbar circuitry. STMicroelectronics no longer manufactures this exact variant in the TO-220FP package. ## Dropout voltage and quiescent current — the trade-offs Maximum dropout is 2 V at 1 A typical, so a 7 V input is the practical minimum to hold a clean 5 V output at full load. Quiescent current runs 6 mA — negligible for a linear regulator driving a 1.5 A load, but worth noting if the rail is always-on in a battery-backed system. The 6 mA Iq flows to ground regardless of load, so a lightly loaded rail wastes about 30 mW at 5 V output.","metaTitle":"STMicroelectronics L7805ACP Linear Regulator","metaDescription":"STMicroelectronics L7805ACP fixed 5V positive linear regulator, 1.5A output, TO-220FP package. 68 dB PSRR at 120 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"STMicroelectronics","PSRR":"68dB (120Hz)","Series":"-","Package":"Tube","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"1.5A","Base Product Number":"L7805","Protection Features":"Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"0°C ~ 125°C","Voltage - Input (Max)":"35V","Voltage Dropout (Max)":"2V @ 1A (Typ)","Voltage - Output (Max)":"-","Supplier Device Package":"TO-220FP","Current - Quiescent (Iq)":"6 mA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3000","priceTiers":[{"qty":1,"price":"$1.36000","currency":"USD"},{"qty":10,"price":"$1.22000","currency":"USD"},{"qty":25,"price":"$1.15760","currency":"USD"},{"qty":100,"price":"$0.95080","currency":"USD"},{"qty":250,"price":"$0.88880","currency":"USD"},{"qty":500,"price":"$0.78546","currency":"USD"},{"qty":1000,"price":"$0.68250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1ec3c1a4c11b806c0cf815b616dfcd1d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/L7805ACP/alternatives.json"},"ai":{"faq":[{"question":"Can I use L7805CV instead of L7805ACP?","answer":"The L7805CV is a functional alternative in the standard TO-220 package, but the L7805ACP uses the TO-220FP full-pack (fully insulated) package.
