It comes in a TO-220-3 through-hole package, suited for board-level power conditioning where a clean 5 V rail is needed from a higher DC input. Maximum dropout voltage is 1.2 V at 800 mA output. Power-supply rejection ratio is 75 dB at 120 Hz. ## Protection and temperature range Built-in over-current and over-temperature protection guard against fault conditions. The LD1117V50 is officially obsolete per the manufacturer's lifecycle status. No factory orders are accepted; availability is limited to surplus and broker inventory.","metaTitle":"STMicroelectronics LD1117V50 LDO Regulator, 5V Fixed, 800mA","metaDescription":"STMicroelectronics LD1117V50 positive fixed LDO regulator, 5V output at 800mA, 1.2V dropout, 75dB PSRR.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"STMicroelectronics","PSRR":"75dB (120Hz)","Series":"-","Package":"Tube","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"800mA","Base Product Number":"LD1117","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"0°C ~ 125°C","Voltage - Input (Max)":"15V","Voltage Dropout (Max)":"1.2V @ 800mA","Voltage - Output (Max)":"-","Supplier Device Package":"TO-220","Current - Quiescent (Iq)":"10 mA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/494bb92f4effb270dec91ee8a399de6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LD1117V50/alternatives.json"},"ai":{"faq":[{"question":"Is LD1117V50 obsolete?","answer":"Yes, the manufacturer lists LD1117V50 as obsolete.
