L7983 Synchronous Step-Down Switching Regulators STMicroelectronics L7983 Synchronous Step-Down Switching Regulators deliver up to 300mA DC based on peak current mode architecture with output voltage adjustability ranges from 0.85V to VIN. The monolithic L7983 regulators offer a wide input voltage range and adjustable UVLO threshold to meet the specification for the 12V, 24V, and 48V industrial bus standards. A soft-start time is internally fixed and an output voltage supervisor manages the reset phase for any digital load (microcontroller, FPGA, etc.). The internal compensation network features high noise immunity, simple design, and saves on the component cost.
