BU2ATD2WNVX-TL

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

The BU2ATD2WNVX-TL is a single-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 2.1 V with a maximum output current of 200 mA. The device operates within an input voltage range of 1.7 V to 6 V and features a typical power supply rejection ratio (PSRR) of 70 dB. It utilizes the SSON004X1010-4 surface-mount package, measuring 1.0 mm x 1.0 mm x 0.6 mm. The regulator maintains a typical dropout voltage of 380 mV at full load and consumes only 35 uA of quiescent current. It supports operation from -40°C to +85°C.
