PRODUCTION DATA
An undervoltage-lockout circuit prevents misoperation of the device at input voltages below 2.5 V (typical). When the input voltage is below the UVLO threshold, the device remains off and the internal power MOSFET turns off. The UVLO threshold is set below the minimum operating voltage of 2.9 V to ensure that a transient VIN dip does not cause the device to reset. For the input voltages between UVLO threshold and 2.9 V, the device attempts to operate, but the electrical specifications are not ensured.
