Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2: As long as TA ≤ +85C, all electrical characteristics hold true for the 3.0V and 3.3V options at all current loads and the 2.5V option at all loads when VIN
≤ 5V. For VIN > 5V with the 2.5V option, the junction temperature rise above ambient is: T = 540IL23 where IL is in amps. The output current must be derated
at higher ambient temperatures to make sure TJ does not exceed 150C when operating the 2.5V option at VIN > 5V.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin.
Note 4: The VOUT pin is forced to 200 mV above the typical VOUT. This is to insure that the internal switches are off.
Note 5: The output capacitor COUT is fully discharged before measurement.
