FEATURES
►SIP-Package 11.5x7.55x10.2 mm ►Pin-out compatible with LM78xx Linear Regulators ►Very high Efficiency up tp 97% ►Excellent Line/Loads Regulation ►Low Ripple and Noise ►Short Circuit Protection ►Operating Temp.Range -40°C to +90°C ►Thermal Shutdown ►Low Stand-by Current ►3 Years Product Warranty PRODUCT OVERVIEW The MINMAX M78A series is a new range of switching regulators designed as a dropVin replacement for old LM78xx linear regulators with low efficiency.The very high efficiency of these stepVdown converters allow an operating temperature up to 80°C at fullVload without need of any heatsink. The regulators come in a package which fits in the standard TOV220 footprint of linear regulators. The high efficiency and low standVby power consumption of these switching regulators offer the designer a new, costVefficient solution for many applications.

Suggested capacitor CHEMIVCON KY 330µF/100V. 5 That “natural convection” is about 20LFM but is not equal to still air (0 LFM). 6 With a input capacitor 22µF/50V for input voltage > 28VDC, the input voltage allows 32VDC, max. 7 Specifications are subject to change without notice.
