BU33TA2WHFV-TR

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

The BU33TA2WHFV-TR is a single-channel CMOS Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 3.3 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. Key electrical specifications include a quiescent circuit current of 40 µA, a ripple rejection ratio of 65 dB, line regulation of 2 mV, and load regulation of 20 mV. It is housed in an HVSOF-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

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

Verify the specific suffix WHFV to confirm the HVSOF-5 package type and tape/reel packaging configuration. Confirm RoHS compliance status through official datasheets or manufacturer documentation before integration. Ensure the component is suitable for non-automotive applications as per standard classification.

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

Select this regulator for designs requiring a compact footprint due to the small HVSOF-5 package dimensions. It is appropriate for battery-powered devices where low quiescent current extends operational life. Verify that the required output current does not exceed 200 mA and that the input voltage remains within the specified 2.5 V to 5.5 V window.

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

This component belongs to the BU**TA2WNVX/HFV series of high-performance Full CMOS regulators. The series is characterized by its ultra-small package options, specifically SSON004X1216 and HVSOF5, designed for space-constrained portable electronics. The technology focuses on minimizing power dissipation while maintaining stable regulation under varying load conditions.

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

BU33TA2WNVX-TR offers identical electrical performance but utilizes the SSON004X1216 package instead of HVSOF-5. Designers must verify pinout compatibility and thermal characteristics when substituting between these package variants.
