Description
The R-78T is a switching regulator with a wide input voltage range and a low profile SMD package. Three output
voltages are available as standard: 3.3V, 5V and 12V. Due to the 1.5A start-up overload capability, the R-78T can
be used to replace 1A or 1.5A regulators in many applications. These modules come with three different styles to
be pin-compatible with existing solutions, but at a lower cost.
