Inverting buck-boost regulator in SOIC-8
The MAX765ESA+T is an inverting buck-boost (step-up/step-down) switching regulator from Analog Devices, delivering a regulated negative output from a positive input rail. It generates an adjustable output from -1V down to -16V, drawing from a 3V to 16V input — useful when a board has only a positive supply but needs a clean negative rail for op-amps, bias circuits, or LCD contrast. Switching at 300 kHz, the part delivers up to 120 mA continuous output.
The Tape & Reel (TR) packaging option (also available as Cut Tape, CT) is suited for production pick-and-place or small-batch prototyping. The reel quantity is typical for this package size — a full reel covers a moderate production run without frequent reel changes.
It fits outdoor telecom gear, factory-floor sensors, and automotive cabin electronics that see moderate thermal cycling but not under-hood extremes.
