BU18JA2VG-C
200mA 1.8V, Fixed Output, High PSRR, High-Accuracy CMOS LDO Regulator for Automotive

BU18JA2VG-C is high-performance CMOS LDO regulators with output current ability of up to 200mA. The SSOP5 package can contribute to the downsizing of the set. This device has excellent noise and load response characteristics despite of its low circuit current consumption of 33μA. It is most appropriate for various applications such as power supplies for radar modules and camera modules.
