ELECTRICAL CHARACTERISTICS (continued)
(V
Typical values are at T
Note 1: Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature (T
Note 2: (V
Note 3: Dropout Voltage is (V
Note 4: Foldback Current Limit was characterized by pulse testing to remain below the maximum junction temperature.
Note 5: The Reverse-Current Protection Threshold is the output/input differential voltage (V
Note 6: Noise is tested using a bandpass amplifier with two poles at 10Hz and two poles at 10kHz.
