Switching at 63 kHz means the inductor value lands in the 47-220 µH range for most designs — larger than a 500 kHz part would need, but the switching losses stay low enough that the SOIC-8 package can dissipate the heat without a heatsink in still air up to 85°C ambient. ## Input and output voltage range — where this regulator fits The 2V minimum input lets it start from a near-depleted Li-ion cell or a single alkaline battery, while the 30V maximum input covers 24V industrial rails with margin for transients — the output can be set anywhere from 1.25V up to 50V (limited by the switch breakdown), so a single design can generate a 3.3V logic rail, a 12V bias supply, or a 48V phantom power feed from the same PCB layout. The output configuration accepts positive or negative regulation — the same pinout can generate a -5V rail from a +5V input using the inverting topology, which saves a dedicated negative regulator on the board. ## Active lifecycle and compliance — no obsolescence risk ROHS3 compliant and supplied in a standard tube — the 8-SOIC package is a JEDEC-compatible footprint shared by hundreds of regulators, so the PCB land pattern is well-characterised and the reflow profile is standard lead-free.","metaTitle":"LT1107IS8#PBF Analog Devices Buck Boost Regulator, 1.5A","metaDescription":"LT1107IS8#PBF step-up/step-down adjustable regulator, 1.5A switch, 63kHz, 8-SOIC.
