CMOS LDO Regulator Series for Portable Equipments
Versatile Package
FULL CMOS LDO Regulator
BUxxUB3WG series
●General Description
BUxxUB3WG series is high-performance FULL CMOS
regulator with 360-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.
●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
Package SSOP5 is similar to SOT-23-5 (JEDEC)
Low dropout voltage
