Optimized for MCU power supplies in automotive body and powertrain systems, 16 models of BD4xxMx series utilize 0.35 µm BiC-DMOS processes and ROHM analog design technology to achieve input tolerance of 45 V and minimize no-load current consumption. Circuit design enables support for ceramic capacitors, eliminating need for electrolytic capacitors for oscillation prevention. Stable voltage output with no output fluctuations or oscillation is possible using 1–10 µF external capacitance.
