L5987(2008) Datasheet PDF - STMicroelectronics

Description
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.
