The LD8105GL is an AC-DC Controllers & Regulators ROHS manufactured by Leadtrend in a SOT-26 package. It is a constant frequency, current mode, low dropout power supply controller. It provides auto-restart, short circuit protection, high temperature protection, and the possibilities to adjust the output voltage, the switching frequency, and the minimum ON-time. It operates at a wide input voltage range from 2.6V DC to 17V DC. It can handle a maximum current of 3A, and an output voltage range from 1.23V DC to 13V DC. It is designed for high efficiency, low noise operation, and cost effective solutions for many AC/DC power conversion applications.
