STMicroelectronics LD39150
The LD39150 is a fast ultra low drop linear regulator which operates from 2.5 V to 6 V input supply. The low drop voltage, low noise, and ultra low quiescent current make it suitable for low voltage microprocessor and memory applications. The device is developed on a BiCMOS process which allows low quiescent current operation independently of output load current.| Part No. | LD39150 |
