BU6653NUX-TR

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

The BU6653NUX-TR is a three-channel CMOS LDO regulator from ROHM Semiconductor, designed for portable electronic applications. It operates within an input voltage range of 2.5 V to 5.5 V with a maximum withstand voltage of 6 V. Each channel delivers up to 0.2 A output current with high accuracy of ±1.0% and ±25 mV. Key electrical parameters include a typical dropout voltage of 0.36 V at full load, ripple rejection of 65 dB, and circuit current of 0.12 mA. The device features thermal shutdown, over-current protection, and discharge functions, housed in a compact VSON008x2030 package.

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

Verify the NRND (Not Recommended for New Designs) status before procurement. Confirm that existing inventory meets project requirements as new design sales are restricted. Ensure compatibility with VSON008x2030 footprint and validate thermal performance under expected load conditions. Check RoHS compliance documentation for final assembly integration.

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

Select this component when a multi-output solution is required in a small form factor. Consider the 0.2 A per channel limit and 65 dB ripple rejection for noise-sensitive circuits. Evaluate the -40°C to +85°C operating range against environmental constraints. Compare dropout characteristics with system headroom requirements to ensure stable regulation across the input voltage range.
