General Description

The EC9301A is a series of easy to use fixed and adjustable step-down (buck) switch-mode voltage regulators. These devices are available in fixed output voltage of 3.3V, 5V, and an adjustable output version.
Both versions are capable of driving a 3A load with excellent line and load regulation.
Requiring a minimum number of external components, these regulators are simple to use and include internal
frequency compensation, and a fixed-frequency oscillator.
The output voltage is guaranteed to ±3% tolerance under specified input voltage and output load conditions. The oscillator frequency is guaranteed to ±15%. External shutdown is included, featuring typically 80 μA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions.
The EC9301A is available in TO-220B-5L ,TO220-5L and TO-263-5L packages.
