BDJ2GA3WNUX-TR

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

The BDJ2GA3WNUX-TR is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 12V output with a maximum continuous current of 0.3A. The device operates within an input voltage range of 4.5V to 14V, supporting a maximum withstand voltage of 15V. Key electrical parameters include a typical dropout voltage of 0.6V at full load and a ripple rejection ratio of 60dB. The quiescent circuit current is 0.6mA. It features high accuracy with ±1.0% output voltage tolerance at 25°C and includes built-in thermal shutdown and overcurrent protection circuits.

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

• Integrated overcurrent protection and thermal shutdown circuits to prevent IC damage during short circuits or overload conditions.
• Includes an ON/OFF switch function that reduces circuit current to 0µA when disabled, minimizing power consumption.
• Designed for use with ceramic output capacitors to support system miniaturization and extended component lifespan.
• Features soft start functionality to manage inrush currents and ensure stable startup sequences.

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

Verify the specific suffix WNUX-TR corresponds to the VSON008X2030 package and tape-and-reel quantity of 4000 units. Confirm RoHS compliance status and long-term supply availability commitments directly with the manufacturer or authorized distributors before finalizing procurement plans.

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

Select this component when a fixed 12V output is required from a higher input rail up to 14V. Ensure the application demands a maximum load current of 300mA or less. Verify that the operating temperature range of -25°C to +85°C meets environmental requirements. Note that this standard-grade product is not recommended for automotive equipment applications.

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

This part belongs to the BDxxGA3WNUX series of LDO regulators from ROHM Semiconductor. The series offers 0.3A output capability with high precision. Variants exist for different fixed voltages and adjustable configurations, sharing common protection features and compact packaging options like VSON008X2030 for space-constrained designs.

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

Check for other members of the BDxxGA3WNUX family with different fixed output voltages if the 12V requirement changes. Ensure any substitute maintains the same VSON008X2030 footprint and pinout compatibility for direct board replacement without schematic modifications.
