The L5983 is a step-down switching regulator with a 1.5A DC output current, 2.9V to 18V input voltage range, adjustable output voltage starting from 0.6V, programmable switching frequency up to 1MHz, internal soft-start and inhibit, low dropout operation with 100% duty cycle, voltage feed-forward, zero load current operation, overcurrent and thermal protection.
The L5983 is a step-down switching regulator with a 2.0 A (min.) current limited embedded power MOSFET, capable of delivering an output current in excess of 1.5 A DC. It operates with an input voltage range from 2.9 V to 18 V and allows the output voltage to be set from 0.6 V to the input voltage. The device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.
