L5987 Datasheet 3a Step-down Switching Regulator

Manufacturer: STMicroelectronics

Overview: .. L5987 3 A step-down switching regulator Preliminary Data.

General 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.

Key Features
