CMOS LDO Regulator Series for Automotive
Ultra-Small Package
FULL CMOS LDO Regulator
BUxxJA2MNVX-C series
General Description
BUxxJA2MNVX-C series are high-performance FULL
CMOS regulators with 200mA output, which are mounted
on versatile package SSON004R1010 (1.00mm x 1.00
mm x 0.60mm). These devices have excellent noise
characteristics and load responsiveness characteristics
despite its low circuit current consumption of 35μA. They
are most appropriate for various applications such as
power supplies for radar and camera of the automotive.
