Description
The L5986 is a step-down switching regulator with a 3.0 A (min.) current limited embedded
Power MOSFET, so it is ableto deliver up to 2.5 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 thatcan be externally adjusted up to 1 MHz.
The QFN and the HSOP packages with an exposed pad allow reducing the RthJA down to
60 °C/W and 40 °C/W respectively.
Features
2.5 A DC output current
2.9 V to 18 V input voltage
