BU11TD2WNVX-TL

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

The BU11TD2WNVX-TL is a single-channel CMOS LDO regulator from ROHM Semiconductor, housed in an SSON004X1010 package (1.0mm x 1.0mm x 0.6mm). It delivers a fixed output voltage of 1.1V with a maximum output current of 200mA. The device operates within an input voltage range of 1.7V to 6V and withstands up to 6.5V. Key electrical parameters include a typical dropout voltage of 0.8V at full load, a ripple rejection of 70dB, and a circuit current of only 35μA. It features ±25mV accuracy at 25°C, thermal shutdown, over-current protection, and a discharge function.

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

Verify the complete part number including the suffix TL against official ROHM documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status as indicated in the latest datasheet. Check for any specific handling requirements associated with the ultra-small SSON004X1010 package during assembly. Ensure the selected variant matches the required fixed output voltage and current capabilities for the target application.

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

Select this component when a compact footprint and low standby current are critical for portable or battery-operated devices. The 200mA output capability suits moderate load applications such as sensor interfaces or small microcontrollers. Consider the 1.1V fixed output specifically for logic families requiring this rail. Verify that the input voltage range aligns with the system's power source constraints.

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

This part belongs to the BU**TD2WNVX series of high-performance full CMOS regulators. These devices are designed for applications requiring low noise and fast load response. The series utilizes advanced CMOS technology to minimize power consumption while maintaining stable regulation. The SSON004X1010 package represents one of the smallest form factors available for this class of linear regulators.

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

Check for direct pin-compatible substitutes within the same BU**TD2WNVX family with different output voltages if the 1.1V specification does not match the final design requirement. Verify that alternative packages like SSOP5 are acceptable if board space allows for larger footprints.
