PRODUCT OVERVIEW
The MINMAX M78SA series is a new range of switching regulators designed as a drop-in replacement for old LM78xx linear regulators with low
efficiency.The very high efficiency of these step-down converters allow an operating temperature up to 80°C at full-load without need of any heatsink.
The high efficiency and low stand-by power consumption of these switching regulators offer the designer a new, cost-efficient solution for many applications.
