BD30GA3WNUX-TR

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

The BD30GA3WNUX-TR is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3.0V output with a maximum current capacity of 0.3A. The device operates within an input voltage range of 4.5V to 14V, supporting a maximum withstand voltage of 15V. It features high accuracy with ±1% output voltage tolerance at 25°C and includes built-in protection circuits for overcurrent and thermal shutdown. The component is housed in a compact VSON008x2030 package suitable for surface mount applications.

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

Verify the specific suffix WNUX-TR confirms the VSON008x2030 package and tape-and-reel quantity of 4000 units. Confirm RoHS compliance status as indicated in official documentation. Ensure the application environment remains within the specified -25°C to 85°C operating temperature range. Check for any automotive qualification requirements if intended for vehicle use, as this standard-grade part is not recommended for such applications.

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

Select this component when a fixed 3.0V rail is required with moderate current demands up to 300mA. It is suitable for designs prioritizing small footprint due to the VSON package. Consider alternatives if higher current capability or adjustable output voltage is needed. Verify that the input voltage never exceeds the 15V absolute maximum rating during transient conditions.

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

This part belongs to the BDxxGA3W series of LDO regulators from ROHM. The series offers 0.3A output current with high precision. Variants exist for different fixed voltages (e.g., BD33GA3WNUX-TR for 3.3V) and adjustable outputs (BD00GA3WNUX-TR). The GA3 designation typically indicates the specific performance grade and feature set including protection circuits.

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

Direct functional substitutes include BD33GA3WNUX-TR for 3.3V output or BD00GA3WNUX-TR for adjustable output within the same package family. Cross-reference with other ROHM LDOs in the BDxxGA3WEFJ series if HTSOP-J8 packaging is acceptable instead of VSON.
