BU2JTA2WNVX-TR

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

The BU2JTA2WNVX-TR is a single-output linear voltage regulator from ROHM Semiconductor, classified as a CMOS LDO. It provides a fixed output voltage of 2.85V with a maximum continuous output current of 200mA. The device operates within an input voltage range of 3.0V to 6.0V and features a typical power supply rejection ratio (PSRR) of 65dB at 1kHz. It utilizes the SSON004X1216 package, measuring 1.2mm x 1.6mm x 0.6mm. The component supports an operating temperature range from -40°C to +85°C and includes protection mechanisms such as thermal shutdown and over-current protection.
