BU1CTD2WNVX
200mA 1.25V, Fixed Output, High PSRR, High-Accuracy CMOS LDO Regulator

BUxxTD2WNVX series is high-performance FULL CMOS regulator with 200-mA output, which is mounted on microminiature package SSON004X1010 (1.0 mm ? 1.0 mm ? 0.6 mm). It has excellent noise characteristics and load responsiveness characteristics despite its low circuit current consumption of 35µA. It is most appropriate for various applications such as power supplies for logic IC, RF, and camera modules. Micro miniature SSON004X1010 with built-in heatsink is adopted for the package, which contributes to the space-saving design of the set.
