BD30HA3WEFJ-E2

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

The BD30HA3WEFJ-E2 is a fixed-voltage Low Dropout (LDO) regulator from the BDxxHA3WEFJ series, manufactured by ROHM Semiconductor. It provides a stable 3.0V output with a maximum current of 0.3A and an accuracy of ±1.0% at 25°C. The device operates within an input voltage range of 4.5V to 8V, featuring a typical dropout voltage of 0.6V at full load. It includes overcurrent protection, thermal shutdown, and a shutdown function that reduces circuit current to 0µA. The component is housed in an HTSOP-J8 package and supports ceramic capacitors for stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated overcurrent protection and thermal shutdown circuits prevent IC damage during short circuits or overload conditions.
• Features a dedicated on/off switch function that reduces operating current to 0µA when disabled.
• Designed for use with ceramic output capacitors to support system miniaturization and longevity.

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

Verify the complete part number including the suffix -E2 for RoHS compliance status. Confirm the HTSOP-J8 package type matches your PCB footprint requirements. Ensure input voltage does not exceed the 8V maximum rating. Check for any specific handling instructions regarding ceramic capacitor selection as noted in the datasheet.

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

Select this component when a fixed 3.0V output is required with moderate current demands up to 300mA. It is suitable for applications where low quiescent current and high accuracy are prioritized. Consider the 4.5V minimum input voltage constraint against your supply rail. The HTSOP-J8 package offers thermal advantages for compact designs.
