BA50DD0WT

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

The BA50DD0WT is a fixed output linear low-dropout regulator manufactured by Rohm Semiconductor, designed for positive voltage regulation with a single output channel. It supports a maximum output current of 2A and features a typical dropout voltage of 0.7V at full load. The device accepts an input voltage range up to 25V and provides a fixed output voltage of 5V with ±1.0% accuracy at 25°C. Key electrical specifications include a ripple rejection ratio of 55dB at 120Hz and a circuit current of 120µA. It operates within a temperature range of -40°C to 125°C and utilizes a TO-220FP-5 through-hole package.
