BU6652NUX-TR

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

The BU6652NUX-TR is a low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor, designed for stable voltage regulation in compact electronic systems. It features a VSON-8 package and supports an input voltage range from 2.5V to 5.5V. The device provides a fixed output voltage of 2.8V with a maximum output current of 0.2A. Key electrical specifications include a typical ripple rejection of 65dB, line regulation of 2mV, and load regulation of 10mV. It operates within a temperature range of -40°C to +85°C and includes built-in protection circuits such as thermal shutdown and over-current protection.

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

Verify the NRND (Not Recommended for New Designs) status before procurement, as this indicates the component is likely being phased out. Confirm that existing inventory meets project requirements since future availability may be limited. Ensure compatibility with the 2.8V fixed output specification, as alternative variants in the series offer different voltages. Validate that the VSON-8 package dimensions align with the target PCB footprint and soldering process capabilities.

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

Select this component only if a fixed 2.8V output is strictly required and the 0.2A current capacity suffices for the load. Consider the NRND status carefully; new designs should evaluate newer alternatives unless cost or legacy constraints dictate otherwise. Verify that the 2.5V minimum input voltage allows sufficient headroom for the intended application's supply variations. Ensure the operating temperature range of -40°C to +85°C covers the environmental conditions of the final product.

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

The BU6652NUX-TR belongs to the BU6652NUX series of three-channel CMOS LDO regulators from ROHM Semiconductor. This series is characterized by high accuracy, high ripple rejection, and integrated safety features. The specific model provides a single fixed 2.8V output among its channels, packaged in a small VSON-8 form factor suitable for modern portable electronics.

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

Check for direct pin-compatible substitutes within the same ROHM family that may have updated lifecycle statuses. Evaluate other manufacturers' LDOs offering 2.8V output and similar current ratings if supply continuity is a concern.
