Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. Conditions for which the device is intended to be functional is indicated by operating ratings, but specific performance limits isn’t be guaranteed. To make sure of specifications and test conditions, read Electrical Characteristics. Only for the test conditions listed the guaranteed specifications can be applied. When the device is not operated under the listed test conditions some performance characteristics may degrade. 2. Devices must be derated based on package thermal resistance at elevated temperatures. 3. The most likely parametric norm represents at 25°C. 4. The LR1107/E output must be diode-clamped to ground. If used in a dual-supply system where the regulator load is returned to a negative supply. 5. Between the VIN and VOUT terminals the output PMOS structure contains a diode. This diode is reverse biased normally. If the voltage at the output terminal is forced to be higher than the voltage at the input terminal this diode will get forward biased. This diode can withstand 650mA of peak current and 120mA of DC current typically. 6. Output voltage line regulation is the change in output voltage from the nominal value which is due to change in the input line voltage. Which is defined as the change in output voltage from the nominal value due to change in load current is output voltage load regulation. The load regulation and line regulation specification include the typical number only. But, the limits for load and line regulation are included in the output voltage tolerance specification. 7. ERROR Flag hysteresis and threshold are specified as regulated output voltage’s percentage. 8. At which the output drops 2% below the normal value dropout voltage is defined as the minimum input to output differential voltage. Only to output voltages of 2.5V and above dropout voltage specification applies. For output voltages below 2.5V, since the minimum input voltage is 2.5V, the drop-out voltage is nothing but the input to output differential. 9. Specification has been tested at −40°C≤TJ≤ 85°C cause under shutdown conditions the temperature rise of the device is negligible. 10. The minimum operating VIN value is equal to VOUT(NOM) + VDROPOUT] or 2.5V, just the greater.
