BU32TA2WNVX-TR

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

The BU32TA2WNVX-TR is a single-output fixed low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 3.2 V with a maximum output current of 200 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and features a typical dropout voltage of 300 mV at full load, with a maximum of 600 mV. It incorporates a shutdown function and offers a typical power supply rejection ratio (PSRR) of 65 dB. The regulator maintains a quiescent current of 40 µA and ensures voltage regulation accuracy of ±1% at 25°C. It is housed in a compact SSON004X1216 surface-mount package.

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

Verify the specific suffix and tape/reel specifications against the manufacturer's latest datasheet before procurement. Confirm that the SSON004X1216 package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives and check for any lead-free or whisker-resistant requirements relevant to the assembly process. Cross-reference the ordering code with authorized distributors to ensure authenticity and traceability.

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

Select this component when a stable 3.2 V rail is required for sensitive analog or digital loads within a 2.5 V to 5.5 V input window. The low quiescent current makes it suitable for battery-operated devices where standby power consumption is critical. The small SSON004X1216 package aids in space-constrained designs. Consider the thermal dissipation capabilities if operating near the maximum current limit or ambient temperature extremes.
