The LV5980MC regulates input voltages from 4.5V to 23V down to an output voltage as low as 1.235V. Combining a low consumption power saving feature, the device shows an operating current of 63uA, with both pulse-width modulation (PWM) and pulse-frequency modulation (PFM). It can achieve 80% efficiency at an output current of 2mA in typical applications. The device also includes an internally fixed switching frequency of 370kHz, high-side MOSFET of 100 milliohms and is able to supply up to 3.0 A of load current. The LV5980MC is offered in a SOIC-8 package.
