BD4xS5-C Fixed Output LDO Regulators

ROHM Semiconductor BD4xS5-C Fixed Output Low Dropout (LDO) Regulators are engineered for high-reliability applications in automotive and industrial systems. These regulators offer fixed output voltages ranging from 1.8V to 5.0V, with a wide input voltage range up to 45V, making the regulators suitable for use in environments with fluctuating or high-voltage power sources. Designed to meet AEC-Q100 automotive standards, the ROHM Semiconductor BD4xS5-C series is ideal for powering Electronic Control Units (ECUs), Advanced Driver Assistance Systems (ADAS), infotainment systems, and industrial control units. Key features include a low dropout voltage, low quiescent current, and built-in protection functions such as overcurrent protection (OCP), thermal shutdown (TSD), and output discharge. Housed in compact packages, these regulators support space-constrained designs while ensuring stable and efficient power delivery to microcontrollers, sensors, and communication modules.
