CMOS LDO Regulator Series for Portable Equipments
Versatile Package
FULL CMOS LDO Regulator
BUxxTD3WG series
●General Description
BUxxTD3WG series is high-performance FULL CMOS
regulator with 200-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 35μA. It is most appropriate for
various applications such as power supplies for logic IC,
RF, and camera modules.ROHM’s.
