Table 3. ELECTRICAL OPERATING CHARACTERISTICS (Note 3)
(VIN = VOUT + 1.0 V, VEN = High, IOUT = 100 mA, CIN = COUT = 1 mF, ambient temperature of 25°C (over recommended operating
conditions unless specified otherwise). Bold numbers apply for the entire junction temperature range.)

3. Specification for 2.80 V output version unless specified otherwise.
4. Dropout voltage is defined as the input−to−output differential at which the output voltage drops 2% below its nominal value measured at 1 V
differential. During test, the input voltage stays always above the minimum 2.3 V.
5. Specification for 1.8 V output version.
6. For VOUT < 2.0 V, the initial accuracy is ±2% and across temperature ±3%.
