3 A Step-down Switching Regulator

The L5987 is a step down Switching Regulator with 3.5 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 conditionals Section 5.7 and Section 5.8). 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 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 QFN and the HSOP package with exposed pad allow reducing the RthJA down to 60 C/W and 40 C/W respectively. By STMicroelectronics
