BU2KUA3WNVX-TL

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

The BU2KUA3WNVX-TL is a single-output low-dropout (LDO) linear voltage 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 at full load. It features a power supply rejection ratio (PSRR) of 70 dB and maintains a quiescent current of 50 µA. The component is housed in a compact DFN-4 package, suitable for surface-mount applications.

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 levels may be limited or discontinued. Ensure compatibility with existing PCB footprints and thermal requirements. Check for alternative components if long-term supply assurance is required for production cycles.

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

Select this regulator when a fixed 2.0 V output is required from a 1.7 V to 5.5 V input source. Consider its 300 mA current capability and 50 µA quiescent current for efficiency needs. The DFN-4 package suits space-constrained layouts. Evaluate thermal performance under expected load conditions to ensure operation within the -40°C to +85°C temperature range without exceeding power dissipation limits.

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