CMOS LDO Regulator Series for Portable Equipments
Versatile Package
FULL CMOS LDO Regulator
BUxxUA3WNVX series
●General Description
BUxxUA3WNVX series is high-performance FULL
CMOS regulator with 300-mA output, which is mounted
on versatile package SSON004X1010 (1.00mm × 1.00
mm × 0.60mm). 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.
●Features
