    The L5987 is a step-down switching regulator with a 3.5 A (minimum) current limited embedded Power MOSFET, so it is able to deliver an up to 3 A current to the load depending on the application conditions.


    The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN. Having a minimum input voltage of 2.9 V, the device is suitable also for a 3.3 V bus.


    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 VFQFPN8 and the HSOP packages with an exposed pad allow reducing the RthJAdown to 60 °C/W and 40 °C/W respectively.
