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.
