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 High accuracy detection low current consumption Compatible with small ceramic capacitor (Cin=Co=1.0uF) With built-in output discharge circuit High ripple rejection ON/OFF control of output voltage With built-in over current protection circuit and thermal shutdown circuit Low dropout voltage
