BD50C0AWFP-E2

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

The BD50C0AWFP-E2 is a high-side low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 5 V output with a maximum load current of 1 A. The device operates within an input voltage range of 4 V to 26.5 V and features a typical dropout voltage of 300 mV at 500 mA, with a maximum of 500 mV. It includes internal overcurrent protection and thermal shutdown circuits for reliability. The regulator is housed in a TO-252-5 surface-mount package and is qualified under the AEC-Q100 standard for automotive applications.

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

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure the component meets the required AEC-Q100 grade for your target application environment. Cross-reference the package marking with the official ROHM documentation to distinguish between similar variants in the BD series.

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

Select this regulator when a fixed 5 V output is required from a higher voltage rail up to 26.5 V. The TO-252-5 package offers adequate thermal performance for 1 A loads without excessive heatsinking. Consider the 300 mV typical dropout when designing for minimum input-output differential constraints.
