M78A
Switching
Regulator 0.5A, SIP Package
PRODUCT OVERVIEW
The MINMAX M78A 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
regulators come in a package which fits in the standard TO-220 footprint of linear
regulators. The high efficiency and low stand-by power consumption of these switching
regulators offer the designer a new, cost-efficient solution for many applications.
