BD50FD0WHFP-TR

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

The BD50FD0WHFP-TR is a fixed-output low saturation linear regulator from the BDxxFD0 series, manufactured by ROHM Semiconductor. It provides a fixed 5V output with a maximum continuous current of 2A. The device supports an input voltage range from 6V to 32V and withstands up to 35V. Key electrical parameters include a typical dropout voltage of 0.40V at 1A load, a ripple rejection ratio of 55dB, and output accuracy of ±1.0% at 25°C. It operates within a temperature range of -40°C to 105°C.
