CMOS LDO Regulator Series for Portable Equipments
FULL CMOS LDO Regulator
BUxxUC3WG series is high-performance FULL CMOS
regulator with 300-mA output, which is mounted on
versatile package SSOP5 (2.9 mm × 2.8 mm × 1.25 mm).
It has excellent noise characteristics and load
responsiveness characteristics despite its low circuit
current consumption of 50μA. It is most appropriate for
various applications such as power supplies for logic IC,
RF, and camera modules ROHM’s.
