Product Description

K78xx-1000R3(L) series are high efficiency switching regulators and ideal substitutes for LM78xx series three-terminal linear regulators. The converters feature high efficiency, low loss, short circuit protection, positive or negative output voltage, and there is no need for a heat sink. These products are widely used in applications such as industrial control, instrumentation and electric power.

①For input voltage exceeding 30 VDC, an input capacitor of 22uF/50V is required;

② L-suffix: Add L-suffix for horizontal mount with 90 degree angled pins (K78xx-1000R3L)
