R-78T-1.0
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.
