BD00KA5WFP-E2

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

The BD00KA5WFP-E2 is a low-dropout voltage regulator manufactured by ROHM Semiconductor, housed in a TO-252-5 surface-mount package. It provides a single positive output with an adjustable voltage range from 1.0 V to 3.3 V. The device supports a maximum output current of 500 mA and operates within an input voltage window of 2.3 V to 5.5 V. Key electrical specifications include a typical ripple rejection ratio of 50 dB, a maximum dropout voltage of 200 mV, and a power dissipation rating of 1.3 W. It functions reliably across an extended temperature range from -40 °C to +105 °C.

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

Verify the specific suffix E2 indicates compliance with RoHS directives and REACH SVHC requirements before procurement. Confirm the TO-252-5 package variant matches your PCB footprint constraints. Ensure the adjustable output configuration aligns with your external resistor network design rather than assuming a fixed voltage level.

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

Select this component when an adjustable output between 1.0 V and 3.3 V is required within a compact TO-252-5 form factor. It is suitable for applications needing 500 mA load current with minimal voltage drop. Consider the 1.3 W power dissipation limit and thermal management needs when designing for high input-output differentials or ambient temperatures near the upper operational limit.

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

This part belongs to the BD00KA5WFP series of secondary LDO regulators designed for miniaturization and energy efficiency. Unlike fixed-output variants such as the BD18KA5WFP-E2, this model allows voltage customization via external feedback resistors. It shares core protection features like thermal shutdown and overcurrent limiting with other members of the KA5 family.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct functional substitutes include other ROHM adjustable LDOs in similar packages, such as the BD00KA5WF-E2 if SOP-8 packaging is acceptable. For fixed 3.3 V outputs, the BD33KA5WFP-E2 offers identical performance without adjustment components.
