Datasheet
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
