CMOS LDO Regulators
BUxxSA4 series
●General Description
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.
