BU15UA3WNVX-TL

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

The BU15UA3WNVX-TL is a single-output fixed low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 1.5 V with a maximum output 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 280 mV. It is housed in a DFN-4 surface-mount package and supports an operating temperature range from -40°C to +85°C.

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

Verify the supply status before design finalization, as this component may be classified as Not Recommended for New Designs (NRND). Confirm that the DFN-4 package dimensions and pinout match your PCB layout requirements. Ensure the 1.5 V fixed output aligns with your system's voltage rails. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

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

Select this component when a stable 1.5 V rail is required from inputs between 1.7 V and 5.5 V. The 300 mA current capability suits moderate load applications. Consider the 280 mV dropout voltage to ensure sufficient headroom between input and output under full load. The DFN-4 package offers a compact solution for space-constrained designs requiring single-output regulation.

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

This part belongs to the BU15UA3WNVX series of LDO regulators from ROHM Semiconductor. It shares similar electrical characteristics and packaging with other variants in the series, such as the BU25UA3WNVX-TL and BU33UA3WNVX-TL, which offer different fixed output voltages like 2.5 V and 3.3 V respectively, while maintaining the same 300 mA output current and DFN-4 form factor.

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

The BU25UA3WNVX-TL and BU33UA3WNVX-TL are direct functional substitutes within the same series, differing only in their fixed output voltage settings (2.5 V and 3.3 V respectively). These parts share identical packages, current ratings, and electrical specifications aside from the output voltage.
