BD30GA3WEFJ-E2

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

The BD30GA3WEFJ-E2 is a high-accuracy low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed positive output voltage of 3.0 V with a maximum output current capability of 300 mA. The device operates within an input voltage range of 4.5 V to 14 V and features a typical dropout voltage of 600 mV at full load. It is housed in an HTSOP-J8 surface-mount package, suitable for space-constrained designs. The component supports operation across a temperature range from -25°C to +85°C and includes built-in protection circuits for thermal shutdown and overcurrent limiting.

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

Verify the complete part number including the suffix E2 to ensure correct packaging and compliance specifications. Confirm that the required output voltage matches the fixed 3.0 V specification, as adjustable variants exist within the same family. Check datasheet details for thermal performance requirements relative to your specific PCB layout and ambient operating conditions before finalizing procurement.

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

Select this component when a fixed 3.0 V output is required with moderate current demands up to 300 mA. It is appropriate for applications where input voltages vary between 4.5 V and 14 V. Consider the HTSOP-J8 package size constraints and the -25°C to +85°C operating temperature range against your system requirements. Compare dropout characteristics if input-output differential is minimal.
