BU33TA2WNVX-TR

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

The BU33TA2WNVX-TR is a fixed-output positive linear voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3.3 V output with a maximum current capacity of 200 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 65 dB. Key electrical parameters include a dropout voltage of 300 mV (maximum 600 mV at full load), line regulation of 2 mV, and load regulation of 20 mV. Quiescent current is specified at 40 µA, with a maximum power dissipation of 220 mW. It 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 exact part number BU33TA2WNVX-TR against official ROHM Semiconductor documentation to ensure compatibility with your design requirements. Confirm that the SSON004X1216 package dimensions match your PCB footprint specifications. Check for any specific RoHS compliance certificates or material declarations required by your manufacturing standards. Ensure that the operating temperature range of -40°C to +85°C meets your environmental conditions. Validate input voltage constraints between 2.5 V and 5.5 V for proper regulator function.

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

Select this component when a fixed 3.3 V output is required with moderate current needs up to 200 mA. Consider its low quiescent current of 40 µA for battery-operated applications where power conservation is critical. The small SSON004X1216 package makes it suitable for space-constrained designs. Evaluate the 65 dB PSRR if noise sensitivity is a concern in the application environment. Compare dropout voltage characteristics against other LDOs if input voltage headroom is limited.
