BD433M5FP-CE2

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

The BD433M5FP-CE2 is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a nominal output voltage of 3.3V with a maximum load current capability of 500mA. The device operates within an input voltage range from a minimum of 4.6V to a maximum of 42V, featuring a typical dropout voltage of 250mV at 300mA and a ripple rejection ratio of 60dB. It is housed in a TO-252-3 surface-mount package and supports junction temperatures from -40°C to +150°C.

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

Verify the specific suffix CE2 matches your design requirements, as it denotes the standard tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TO-252-3 footprint aligns with your PCB layout constraints. Cross-reference the latest datasheet revision to confirm pinout consistency and electrical characteristics against your schematic specifications.

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

Select this component when a fixed 3.3V rail is required with 500mA capacity and wide input voltage tolerance. It is suitable for designs needing robust thermal performance without external enable pins. Consider alternative packages like HTSOP-J8 if space constraints differ. Verify that the 4.6V minimum input voltage meets your system's lowest operating condition to prevent dropout during transient loads.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the BD433 series of LDO regulators designed for automotive and industrial applications. It shares core electrical characteristics with variants such as BD433S5FP-CE2 but differs in package type and specific thermal or electrical tolerances defined by the suffix.
