BLE6234 LDO Voltage Regulator, 40V Input, 100mA Output, 2.5µA Ultra-Low Quiescent Current, SOT-89-3 Package

The BLE6234 is a high-voltage low-dropout (LDO) linear regulator designed for ultra-low power consumption applications. With an input voltage capability up to 40V and output current up to 100mA, it is ideal for battery-powered and standby-sensitive systems. Its extremely low quiescent current of just 2.5µA significantly improves energy efficiency, while maintaining stable and reliable output regulation. The SOT-89-3 package provides a compact yet thermally efficient solution for industrial and embedded designs.
