BD70GA3WNUX-TR

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

The BD70GA3WNUX-TR is a fixed-voltage output Low Dropout (LDO) regulator from the BDxxGA3WEFJ/BDxxGA3WNUX series, manufactured by ROHM Semiconductor. It provides a maximum output current of 0.3A with an output voltage accuracy of ±1% at 25°C. The device operates within an input voltage range of 4.5V to 14V and features a typical dropout voltage of 0.6V at full load. Key electrical parameters include a quiescent circuit current of 0.6mA, ripple rejection of 60dB, and load regulation of 25mV across the 0 to 300mA range. It utilizes a VSON008X2030 package.

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

• Integrated overcurrent protection and thermal shutdown circuits prevent IC damage during short-circuit or overload conditions.
• Features a dedicated ON/OFF switch function that reduces circuit current to 0µA when disabled.
• Utilizes ceramic capacitors to support system miniaturization and extended lifespan.

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

• Digital home appliances
• General-purpose power management in consumer electronics

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

Verify the specific suffix '-TR' corresponds to the tape-and-reel packaging format containing 4000 units per reel as documented. Confirm RoHS compliance status and ensure the fixed 7.0V output variant matches the design requirement, as the base series includes adjustable options. Check for automotive usage restrictions explicitly stated in the datasheet.

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

Select this component for applications requiring a compact surface-mount solution with high voltage accuracy. The VSON008X2030 package offers excellent thermal performance compared to standard small packages. Ensure the input voltage remains within the 4.5V to 14V window and verify that the 0.3A load capability meets the target circuit demands without exceeding thermal limits.

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

This part belongs to the BDxxGA3WEFJ/BDxxGA3WNUX family of LDO regulators designed for digital equipment. The series distinguishes itself by offering both fixed and adjustable output versions in thermally efficient packages like HTSOP-J8 and VSON008X2030. It is classified as a standard-grade product intended for general commercial use rather than specialized industrial or automotive environments.
