BL8078Q LDO Voltage Regulator, 40V Input, 150mA Low Quiescent Current, SOP-8 Package

The BL8078Q is a high-voltage low-dropout (LDO) linear voltage regulator designed for applications requiring low power consumption and stable output under wide input conditions. Supporting input voltages up to 40V and delivering up to 150mA output current, it provides reliable regulation for industrial, automotive-adjacent, and high-voltage powered systems. Its low quiescent current makes it suitable for standby-sensitive designs, while the SOP-8 package ensures easy integration into compact layouts.
