That input range covers 12V, 24V, and 48V industrial buses, plus automotive battery rails during load-dump transients, without needing a separate pre-regulator. The 150°C junction temperature rating means it handles the thermal load near a motor driver or under-hood electronics without derating — a key spec for the MRO planner stocking spares for a line that runs hot. ## 600mA — right-sized for sensor and control rails 600mA is a mid-current sweet spot. It powers a CAN transceiver, a few op-amps, an MCU core, or a 3.3V sensor chain. It is not sized for a main logic bus or a motor-drive bias rail — that is where the 3A LMR33630APCQRNXRQ1 would come in. The fixed 3.3V output saves two feedback resistors and one BOM line, which matters when you are qualifying a second-source for a tight board. ## Switching frequency and package — layout considerations The switching frequency spreads from 200kHz to 2.2MHz. Lower frequencies keep switching losses down at light load; higher frequencies shrink the inductor and output capacitor. ## Active lifecycle — no LTB scramble The LMR36506RF3RPER carries an Active product status. That means no last-time-buy deadline to track, no sunset date to plan around. For the MRO inventory keeper, this part can be stocked as a slow-moving spare without worrying about obsolescence. The synchronous rectifier inside improves efficiency and reduces the external diode count — one fewer part to stock.","metaTitle":"LMR36506RF3RPER Buck Converter, 3.3V Fixed Output, 600mA","metaDescription":"TI LMR36506RF3RPER step-down buck converter. 3V to 65V input, fixed 3.3V output at 600mA.
