Negative rail from a positive input — what this part does
Rated for 360 mA continuous output, it handles small-signal analog loads — a handful of op-amps or a low-power audio DAC — but not a system-level power bus. The 1.38 MHz switching frequency lets the designer use a small inductor (typically 4.7 µH) and ceramic caps, keeping the total solution footprint under 30 mm².
Package, temperature, and layout realities
Without that, the junction temperature climbs above the 85°C ambient limit in sustained 360 mA operation. Fine for indoor telecom, test equipment, or audio gear; not for under-hood or engine-bay environments.
Sourcing and compliance status
It is ROHS3 compliant.
