CMOS LDO Regulators for Portable Equipments
1ch 500mA
CMOS LDO Regulators
BUxxSD5 series
âGeneral Description
BUxxSD5 series are high-performance CMOS LDO
regulators with output current ability of up to 500mA.
These devices have excellent noise and load response
characteristics despite of its low circuit current
consumption of 33µA. They are most appropriate for
various applications such as power supplies for logic IC,
RF, and camera modules.
