Additional Details

The RP114K291D-TRB is provided in a small DFN(PLP)1010-4 package for high-density board layouts. Its electrical characteristics include a fixed output voltage of 2.9V (as indicated by the part number), a low dropout voltage allowing operation with minimal input-output voltage differential, and excellent ripple rejection performance. Nisshinbo provides comprehensive datasheets containing detailed electrical characteristics, application guidelines, and thermal performance data. The low supply current minimizes power consumption, maximizing battery life in portable devices. The high ripple rejection ensures a stable output voltage even in noisy environments. The integrated short-circuit protection safeguards the device and the connected load from damage in case of accidental short circuits. The small package size allows for easy integration into compact electronic devices.
