BU32TD2WNVX-TL

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

The BU32TD2WNVX-TL is a single-channel, fixed-output CMOS Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. It delivers a maximum output current of 0.2 A with an accuracy of ±1.0% at 25°C. The device operates within an input voltage range of 1.7 V to 6 V and supports a withstand voltage of up to 6.5 V. Key electrical parameters include a typical dropout voltage of 0.22 V at full load, a circuit current consumption of only 35 μA, and a ripple rejection ratio of 70 dB. Load regulation is specified at 10 mV across a load current range from 0.01 mA to 100 mA. The component is housed in an SSON004X1010 package and functions reliably within an operating temperature range of -40°C to +85°C.
