That tab is the output and the primary thermal path — board layout must connect it to a sufficient copper area to keep the junction below 125°C at full load. The -40°C to 125°C junction temperature range covers industrial and outdoor applications: motor drives, outdoor telecom, factory automation, and under-hood automotive auxiliary supplies. Over-current and over-temperature protection are built in. ## Lifecycle and sourcing The LM1085IS-5.0/NOPB carries an Active product status and is ROHS3 compliant. No end-of-life notice or last-time-buy schedule is in effect. For a production BOM line needing a 3A fixed 5V LDO in a TO-263-3 footprint, this part is a current-design fit with no near-term obsolescence risk.","metaTitle":"LM1085IS-5.0/NOPB 3A Fixed 5V LDO Regulator, TO-263-3","metaDescription":"LM1085IS-5.0/NOPB is a 3A fixed 5V LDO regulator in DDPAK/TO-263-3. 68dB PSRR at 120Hz, max dropout 1.5V at 3A.
