OVERVIEW

The MINMAX M78AR-1 series is a range of switching regulators designed as a drop-in replacement for old LM78xx linear regulators with low efficiency. 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.
