BU11TD3WG
300mA 固定電壓輸出LDO穩壓器

BDxxGA3WEFJ / BDxxGA3WNUX系列是可提供0.3A輸出電流的穩壓器。輸出精度為±1%。有可使用外接電阻在1.5V~13.0V範圍內任意設置輸出電壓的可變型以及1.5V/1.8V/2.5V/3.0V/3.3V/5V/6V/7V/8V/9V/10V/12V固定輸出型兩種。封裝組件備有散熱性優良的HTSOP-J8和超小型VSON008X2030。可用於數位家電等廣泛用途。本機型內建用於防止因輸出短路等發生IC破壞的過電流保護電路、關斷時使電路電流為0µA的ON/OFF開關、以及防止因過負載狀態等使IC發生熱破壞的溫度保護電路。另外,採用了陶瓷電容,有助於整機的小型化和長壽化。
