BU6655NUX-TR

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

The BU6655NUX-TR is a three-channel CMOS LDO regulator from ROHM Semiconductor, housed in an 8-pin VSON package. It provides fixed output voltages of 1.5V, 1.8V, and 3.3V with a maximum output current of 200mA per channel. The device operates within an input voltage range of 2.5V to 5.5V and maintains a quiescent current of 0.12mA. Key electrical specifications include a ripple rejection of 65dB, load regulation of 10mV (at 1-100mA), and line regulation of 2mV. It features high voltage accuracy of ±1% for the first two channels and ±25mV for the third, with a typical dropout voltage of 0.36V at full load.
