Specification for 2.8 V output version unless specified otherwise. 4. For VOUT < 2.0 V, the initial accuracy is ±2% and across temp is ±3%. 5. 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. 6. Specification for 1.8 V output version. |
