GENERAL DESCRIPTION
At light loads, the regulator operate in low frequency to maintain high efficiency and low output ripples. Current mode control provides tight load transient response and cycle-by-cycle current limit. The LN5058 guarantees robustness with hiccup output short-circuit protection, FB short-circuit protection, start-up current run-away protection, input under voltage lockout protection, hot-plug in protection, and thermal protection. The LN5058 provides output power good indication which is only available in SOT-23-5L package.● Package
