BD00HC0WEFJ-E2

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

The BD00HC0WEFJ-E2 is a single-output adjustable low-dropout regulator manufactured by ROHM Semiconductor. It provides a maximum output current of 1 A with a positive polarity and operates within an input voltage range of 4.5 V to 8 V. The device delivers an adjustable output voltage between 1.5 V and 7 V, regulated with an accuracy of ±1%. Key electrical parameters include a typical dropout voltage of 600 mV at full load, a reference voltage of 800 mV, and a quiescent current of 900 µA. Line and load regulation are specified at 25 mV each.

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

Verify the specific suffix ME2 or E2 when sourcing, as these indicate package or tape/reel variations that do not alter internal functionality. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required operating temperature range and thermal dissipation capabilities for the target application environment.

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

Select this component for applications requiring a 1 A output current with adjustable voltage settings between 1.5 V and 7 V. The HTSOP-J8 package suits surface-mount designs needing moderate thermal performance. Consider the 900 µA quiescent current if power efficiency in active mode is critical. Verify that the input voltage remains within the 4.5 V to 8 V limit to ensure stable regulation and prevent damage.

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

This part belongs to the BD00HC0W series of low-dropout regulators designed for general-purpose use. It is classified as a standard-grade product intended for digital appliances and consumer electronics. Unlike automotive-qualified variants, this series is not recommended for vehicle equipment. It shares the HTSOP-J8 footprint with other members of the family but differs in current rating and voltage specifications.
