BU6650NUX-TR

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

The BU6650NUX-TR is a three-channel CMOS Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. 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 a maximum output current of 0.2 A. The device features high accuracy, specified as ±1.0% for two channels and ±25 mV for the third. It exhibits a typical dropout voltage of 0.36 V at full load and offers a ripple rejection of 65 dB. The quiescent circuit current is 0.12 mA. Integrated protections include thermal shutdown, over-current protection, and an output discharge function. It is housed in a VSON008X2030 package and functions within an operating temperature range of -40 °C to 85 °C.
