BU2AUA3WNVX-TL

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

The BU2AUA3WNVX-TL is a single-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It operates within an input voltage range of 1.7 V to 5.5 V and provides a fixed output voltage of 2.0 V. The device supports a maximum output current of 300 mA with a typical dropout voltage of 200 mV. It features a power supply rejection ratio (PSRR) of 70 dB at 1 kHz and consumes 50 µA of quiescent current. The component is housed in a DFN-4 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

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

Verify the NRND status before procurement, as this indicates the component is not recommended for new designs. Confirm availability through authorized distributors, as stock may be limited or discontinued. Ensure the DFN-4 package compatibility matches your PCB footprint requirements. Review the latest datasheet for any final design-in warnings or alternative recommendations provided by the manufacturer.

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

Select this regulator when a precise 2.0 V output is required from a 1.7 V to 5.5 V input source. Consider its 300 mA current capability and low quiescent current for efficiency-critical applications. Evaluate the DFN-4 package size against available board space. Compare performance metrics such as PSRR and dropout voltage against other LDOs if noise sensitivity or headroom is a primary design constraint.
