Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for BU28TA2WNVX-TR

BU28TA2WNVX-TR

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

The BU28TA2WNVX-TR is a single-output fixed Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 2.8 V output with a maximum load current of 300 mA. The device operates within an input voltage range of 1.7 V to 5.5 V and features a typical dropout voltage of 200 mV. Key electrical specifications include a ripple rejection ratio of 70 dB, line regulation of 2 mV, and load regulation of 25 mV. The quiescent circuit current is 50 uA. It functions reliably across an operating temperature range from -40 C to +85 C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

High-speed load response characteristics suitable for dynamic power demands
Ultra-low power consumption with minimal circuit current draw
Excellent noise performance with high ripple rejection capability

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

Power supply for logic integrated circuits
Power source for radio frequency modules
Power supply for camera module components

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

Verify the specific suffix TR indicates reel packaging when ordering. Confirm the 300 mA output rating matches system requirements rather than assuming standard 200 mA variants. Ensure the SSON004X1216 footprint aligns with PCB layout constraints. Check RoHS compliance documentation for environmental regulations. Validate the fixed 2.8 V output against design specifications before procurement.

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

Select this component when a compact 300 mA LDO is required for low-noise applications. The 200 mV dropout voltage allows operation closer to the output rail compared to standard regulators. The small SSON004X1216 package saves board space. Consider the 50 uA quiescent current for battery-powered designs. Verify thermal dissipation capabilities within the target enclosure environment.

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

This part belongs to the BUxxTA2WNVX series of high-performance CMOS LDO regulators. The series is characterized by ultra-small packages and low circuit currents. It is designed for portable electronic devices requiring efficient power management. The manufacturer specifies it as a standard-grade product not recommended for automotive use.

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

BU28UA3WNVX-TL offers similar functionality but may have different packaging or slight parameter variations. BU29TA2WNVX provides a 2.9 V output instead of 2.8 V. Verify pin compatibility and thermal performance when substituting.
