Description

This is 1.5A step-down switching regulator. L5983 1.5A step-down switching regulator Features - - - - - - - - - - - 1.5A DC output current 2.9V to 18V input voltage Output voltage adjustable from 0.6V 250kH- switching frequency, programmable up to 1MH- Internal soft-start Inhibit Low dropout operation: 100% duty cycle Voltage feed-forward Zero load current operation Over current and thermal protection VQFN3x3-8L package VFQFPN8 3x3 Description The L5983 is a step down switching regulator with 2.0A current limited embedded power MOSFET, so it is able to deliver an output current in excess of 1.5A DC to the load. The input voltage can range from 2.9V to 18V, while the output voltage can be set starting from 0.6V to VIN. Having a minimum input voltage of 2.9V, the device is suitable for also for the 3.3V bus. Requiring a minimum set of external components, the device includes an internal 250kH- switching frequency oscillator that can be externally adjusted up to 1MHz. The QFN package with exposed pad allows r.
