BD90GA3WNUX-TR

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

The BD90GA3WNUX-TR is a fixed-output low-dropout (LDO) voltage regulator from the BDxxGA3WNUX series, manufactured by ROHM Semiconductor. It provides a maximum output current of 0.3 A with an output accuracy of ±1.0% at 25°C. The device operates within an input voltage range of 4.5 V to 14 V and supports a withstand voltage of up to 15 V. Key electrical parameters include a typical dropout voltage of 0.6 V at full load, a ripple rejection of 60 dB, and a quiescent circuit current of 0.6 mA. It features soft start functionality and is housed in a compact VSON008x2030 package.

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

• Integrated overcurrent protection and thermal shutdown circuits prevent IC damage during short circuits or overload conditions.
• Includes an ON/OFF switch function that reduces circuit current to 0 µA when disabled, minimizing power consumption.
• Soft start capability limits inrush current during startup to ensure stable system initialization.
• Compatible with ceramic output capacitors, supporting miniaturization and long-term reliability of the host equipment.

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

Verify the specific suffix and tape-and-reel configuration against the official datasheet before ordering. Confirm that the application environment remains within the specified operating temperature range of -25°C to 85°C. Ensure that the input voltage does not exceed the 14 V maximum limit under any transient conditions. Check for RoHS compliance status if required by your manufacturing standards. Validate that the VSON008x2030 footprint matches your PCB layout design constraints.

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

Select this component when a fixed output voltage is required with high accuracy and minimal external components. It is suitable for applications where space is limited due to its small VSON package. Consider the 0.3 A output current limit to ensure it meets the load requirements without exceeding thermal limits. The built-in protections make it robust for consumer electronics where fault tolerance is critical. Compare dropout voltage specifications against other LDOs if operating near the minimum input voltage threshold.
