The BD450M5FP-CE2 is a high-accuracy, low-quiescent-current linear voltage regulator manufactured by ROHM Semiconductor. Designed for automotive electronic applications, this device provides a fixed 5.0V output with a maximum output current of 500mA, making it suitable for stable power regulation in automotive control circuits and other electronic systems.
The regulator supports an input voltage range of 5.5V to 42V and offers an output voltage accuracy of ±2.0%. Its typical quiescent current of 38μA helps reduce power consumption in applications where low standby current is important.
The BD450M5FP-CE2 features a typical dropout voltage of 0.2V at a load current of 300mA, along with a ripple rejection ratio of 60dB. These characteristics support stable voltage regulation and help reduce input supply fluctuations in suitable circuit designs.
For improved operating reliability, the device integrates overcurrent protection (OCP) and thermal shutdown protection (TSD). It is qualified to the AEC-Q100 Grade 1 automotive reliability standard, supporting applications that require automotive-grade electronic components.
Housed in a compact TO-252-3 (DPAK) surface-mount package, the BD450M5FP-CE2 is suitable for PCB power management designs and automated SMT assembly. Its wide junction temperature range supports demanding thermal conditions when operated within the manufacturer’s specified limits.
