It is built for automotive and industrial environments where a clean, regulated 5V rail is needed from a higher, possibly noisy input bus up to 45V. The part integrates enable, reset, and watchdog control features, plus over-current, over-temperature, and short-circuit protection, reducing external supervisory circuitry. ## PSRR and temperature range – where it earns its keep Power supply rejection ratio is 60 dB at 100 Hz. Junction temperature range spans -40°C to 150°C. ## Package and lifecycle – active, no LTB risk The TLE7278-2GV50 is supplied in a 14-pin SOIC package (PG-DSO-14, 3.90 mm width) for surface-mount assembly.","metaTitle":"Infineon TLE7278-2GV50 LDO Regulator, 5V Fixed, 180mA","metaDescription":"Infineon TLE7278-2GV50 linear voltage regulator: 5V fixed output, 180mA, 36µA quiescent current, 0.5V dropout, PSRR 60dB at 100Hz, -40°C to 150°C, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"60dB (100Hz)","Package":"Bulk","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable, Reset, Watchdog","Current - Output":"180mA","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 150°C (TJ)","Voltage - Input (Max)":"45V","Voltage Dropout (Max)":"0.5V @ 180mA","Supplier Device Package":"PG-DSO-14","Current - Quiescent (Iq)":"36 µA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.37","stockQuantity":0,"priceTiers":[{"qty":219,"price":"$1.37000","currency":"USD"}]},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/Infineon-TLE7278-2-DS-v01_20-EN.pdf?fileId=5546d46259d9a4bf0159f9dfbf303efc","sourceUrl":null},"ai":{"faq":[{"question":"What are the key protection features of TLE7278-2GV50?","answer":"The regulator includes over-current, over-temperature, and short-circuit protection, plus enable, reset, and watchdog control features."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/TLE7278-2GV50","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/TLE7278-2GV50 when reusing this data.
