CMOS LDO Regulators for Portable Equipments

1ch 500mA

CMOS LDO Regulators

BUxxSD5 series

●General Description

BUxxSD5 series are high-performance CMOS LDO

regulators with output current ability of up to 500mA.

These devices have excellent noise and load response

characteristics

despite

of

its

low

circuit

current

consumption of 33µA. They are most appropriate for

various applications such as power supplies for logic IC,

RF, and camera modules.

●Features
