BA30DD0WT

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

The BA30DD0WT is a fixed-output linear low-dropout (LDO) regulator manufactured by Rohm Semiconductor. It provides a nominal output voltage of 3.0V with an accuracy of ±1.0% at 25°C. The device supports a maximum output current of 2A and operates within an input voltage range of 3V to 25V, with a maximum withstand voltage of 35V. Key electrical characteristics include a typical dropout voltage of 0.45V at full load, a ripple rejection ratio of 55dB, and a quiescent circuit current of 0.9mA. It requires a minimum output capacitance of 22µF for stability.
