CMOS LDO Regulators

BUxxSA5WGWZ series

●General Description

●Key Specifications

Input Power Supply Voltage Range:

1.8V to 5.0V

0mA to 500mA

-40℃ to +105℃

3.0V,3.3V

BUxxSA5WGWZ series are high-performance CMOS LDO

regulators with output current ability of up to 500-mA.

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.
