Datasheet
CMOS LDO Regulator for Portable Equipments
High Ripple Rejection,
Low Current Consumption,
Versatile Package
FULL CMOS LDO Regulator (500mA)
BUXXTH5WNVX
General Description
BUXXTH5WNVX is high-performance FULL CMOS
regulator with 500-mA output, which is mounted on
versatile package SSON004X1010 (1.00mm × 1.00 mm
× 0.60mm). It has excellent ripple rejection, noise
characteristics and load responsiveness characteristics
despite its low circuit current consumption of 10µA. It is
most appropriate for various applications such as power
supplies for logic IC, RF, and camera modules.
Features
High accuracy detection
High ripple rejection
low current consumption
Compatible with small ceramic capacitor
(Cin=Co=1.0uF)
With built-in output discharge circuit
ON/OFF control of output voltage
With built-in over current protection circuit
