An under voltage lockout circuit prevents mis-operation of the device at input voltages below 2.5-V (typical). When the input voltage is below the under voltage threshold, the device remains off and the internal switch FET is turned off. The under voltage lockout threshold is set below minimum operating voltage of 2.9V to avoid any transient VIN dip triggering the UVLO and causing the device to reset. For the input voltages between UVLO threshold and 2.9V, the device attempts to operate, but the specifications are not ensured.
