BD00C0AWFPS-ME2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD00C0AWFPS-ME2 is a low-dropout linear regulator manufactured by ROHM Semiconductor, designed for automotive applications with AEC-Q100 qualification. It features an adjustable output voltage range of 3V to 15V and supports a maximum output current of 1A. The device operates within an input voltage window of 4V to 26.5V and utilizes a TO-252S-5 surface-mount package. Key electrical specifications include a typical dropout voltage of 0.3V at 0.5A output, a ripple rejection ratio of 55dB at 120Hz, and a quiescent current of 0.5mA. It functions reliably across an operating temperature range from -40°C to +105°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as not recommended for new designs or discontinued. Confirm that the TO-252S-5 package dimensions match your PCB footprint requirements. Ensure that the external feedback resistors selected provide the desired output voltage within the specified 3V to 15V range while maintaining stability with low ESR output capacitors.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when a robust 1A solution with high input voltage tolerance up to 26.5V is required for automotive environments. It is suitable for designs needing adjustable output voltages with integrated short-circuit and thermal protection. Consider alternative packages if space constraints differ from the TO-252S-5 form factor.
