BD70GA3WEFJ-E2

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

The BD70GA3WEFJ-E2 is a fixed positive low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a stable 7 V output with a maximum current capacity of 0.3 A. The device operates within an input voltage range of 4.5 V to 14 V and maintains a typical dropout voltage of 0.6 V at full load. Key electrical specifications include a quiescent current of 600 µA, line regulation of 1%, and load regulation of 1.5%. It features ±1% output voltage accuracy at 25°C and supports operation from -25°C to +85°C in an HTSOP-J8 surface-mount package.

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

Verify the complete part number including the suffix to ensure correct packaging and temperature grade. Confirm that the application environment remains within the specified -25°C to +85°C operating range. Ensure input voltage does not exceed the 14 V maximum limit to prevent device damage. Check for RoHS compliance documentation if required by specific manufacturing standards.

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

Select this component when a fixed 7 V output is required with moderate current demands up to 300 mA. It is suitable for designs prioritizing output accuracy and built-in protection features over ultra-low quiescent current. Consider alternative packages like VSON008X2030 if board space constraints require a smaller footprint than the HTSOP-J8.
