Electrical Charateristics

Unless otherwise specified, V

IN = 3.0V for the LM4140-1.024 and LM4140-1.250, VIN = 5.0V for all other voltage options, VEN

IN.COUT = 1µF (Note 4), ILOAD = 1mA, TA =TJ = 25˚C. Limits with standard typeface are for TA = 25˚C, and limits in

boldface type apply over 0˚C to 70˚C temperature range.
