What this regulator does and where it fits
The Analog Devices LT1107CS8#PBF is a current-mode switching regulator that handles step-up (boost) and step-down (buck) conversion from a single chip. Its internal 1.5A switch and wide 2V to 30V input range make it a practical choice for battery-powered equipment, industrial control rails, and multi-rail point-of-load designs where you need positive or negative adjustable outputs down to 1.25V. The 63kHz switching frequency keeps radiated noise low but calls for a larger inductor than a modern 500kHz part would — plan your board area accordingly.
Lifecycle and compliance
Status is Active with ROHS3 compliance, so no end-of-life pressure on new or existing BOMs. The 0°C to 70°C commercial temperature range suits office equipment, appliances, and indoor industrial enclosures — not engine bays or outdoor telecom cabinets. If you need a wider temperature grade, the LT1111IS8#PBF covers -40°C to 105°C with the same 1.5A switch and 72kHz frequency, though it's a different pinout; verify the layout before substituting.
