Typical applications for the LNM operation are car audio, sensors.

3.4.2

Low consumption mode (LCM)

The low consumption mode maximizes the efficiency at the light load. As soon as the output

voltage drops, the regulator generates a pulse to have the FB back in regulation. In order to

minimize the current consumption in the LCM part of the internal circuitry is disabled in the

time between bursts.
