The BA90DD0WHFP-TR from Rohm Semiconductor is a fixed 9V low dropout linear regulator, capable of delivering up to 2A of output current. It features a low dropout voltage of 0.7V at full load and a quiescent current of just 120 µA, making it an efficient choice for high-current applications. The regulator is housed in an HRP-5 package, which is specifically designed for excellent thermal dissipation, ensuring reliable operation under continuous heavy loads. Its stable 9V output is well-suited for automotive, industrial, and telecom applications.
- High Output Current: The 2A current capability supports demanding loads such as infotainment systems, actuators, and LED drivers without the need for external pass elements.
- Excellent Thermal Management: The HRP-5 package is engineered for high power dissipation, allowing the regulator to operate at full 2A load without overheating.
- Low Quiescent Current: Despite its high current rating, the 120 µA quiescent current helps reduce power consumption in standby modes, improving overall system efficiency.
- Low Dropout Voltage: A dropout of just 0.7V at 2A minimizes power loss and allows operation from a 9.7V rail, making it suitable for applications with tight voltage margins.
