Description

General part information

BU2FSA4WGWL Series

BUxxSA4 series are high-performance CMOS LDO regulators with output current ability of up to 200-mA. These devices have excellent noise and load response characteristics despite of its low circuit current consumption of 40µA. They are most appropriate for various applications such as power supplies for logic IC, RF, and camera modules.
