The exposed pad on the PG-SSOP-14 package helps conduct heat to the PCB copper plane; a thermal-via pattern under the pad is recommended to keep junction temperature within limits at full load in hot ambient conditions. ## Sourcing and lifecycle ROHS3 compliant. For new designs, this part carries no last-time-buy risk and is a stable BOM line.","metaTitle":"TLF50281ELXUMA3 Buck Regulator, 5V 500mA, 14-LSSOP, Active","metaDescription":"Infineon TLF50281ELXUMA3 step-down buck regulator, fixed 5V output, 500mA, 4.75-45V input, 2.2MHz switching, -40 to 150°C, PG-SSOP-14.
