BU25UA3WNVX-TL

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

The BU25UA3WNVX-TL is a single-output fixed LDO voltage regulator from ROHM Semiconductor, housed in a DFN-4 package. It provides a 2.5 V output with a maximum current of 300 mA. The device operates within an input voltage range of 1.7 V to 5.5 V and features a typical dropout voltage of 200 mV (max 220 mV). Key electrical parameters include a quiescent current of 50 uA, line regulation of 2 mV, load regulation of 25 mV, and PSRR of 70 dB. It supports surface mount installation and functions between -40°C and +85°C.

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

Verify the component status as NRND (Not Recommended for New Designs) before procurement. Confirm that the DFN-4 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system's environmental specifications. Check for RoHS compliance details if required by your manufacturing standards.

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

Select this component when a 300 mA output current is sufficient for the application. Consider the 2.5 V fixed output against other available voltages in the series. Evaluate the 50 uA quiescent current against lower-power alternatives if battery life is critical. Compare the 200 mV dropout voltage with system headroom requirements.
