The L7986/A is a step-down switching regulator with a 3.7 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 3 A current to the load depending on the application conditions. The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN. Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz. The DFN and the HSOP packages with exposed pad allow reducing the RthJAdown to 60 °C/W and 40 °C/W respectively.
