BU31TA2WNVX-TR

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

The BU31TA2WNVX-TR is a single-output fixed positive Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a nominal output voltage of 3.1 V with a maximum continuous 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 330 mV at full load. It incorporates shutdown functionality, thermal shutdown protection, and overcurrent protection. The component is housed in a compact SSON004X1216 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

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

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required output voltage tolerance and package dimensions for the target PCB layout.

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

Select this component when a stable 3.1 V rail is required for low-power digital or RF loads. Consider the 200 mA current limit and 330 mV typical dropout for headroom calculations. Evaluate the SSON004X1216 footprint against available board space constraints and thermal dissipation requirements.

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

This part belongs to the BU**TA2WNVX series of high-performance FULL CMOS regulators. The series is characterized by ultra-small packages and low circuit current consumption of 40 μA. These devices are designed for applications requiring excellent noise characteristics and fast load response times.

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

BU31UA3WNVX-TL offers a similar 3.1 V output but differs in package type (DFN-4 vs SSON004X1216) and higher output current capability (300 mA). Verify pinout compatibility and thermal performance before substitution.
