The BD35281HFN is an ideal choice for low input voltage to low output voltage applications, and offers high conversion efficiency, which can reduce the size and cost of the power supply line.
The BD35281HFN ultra‑low‑dropout (ULDO) linear regulator operates from a very low input voltage and provides up to 1.5 A output current. It integrates an N‑channel MOSFET power transistor, reducing the input‑to‑output voltage differential to the MOSFET’s on‑resistance level and eliminating the need for external switching components.
Key features include a precise 0.65 V reference, built‑in undervoltage lockout, soft‑start (NRCS) control, short‑circuit and over‑current protection, and a compact HSON8 package. The device is intended for notebook and desktop computers, LCD‑TVs, DVD players and other digital appliances.
