Note 1: Specifications to T A = -40°C are guaranteed by design and not production tested.
Note 2: The MAX6397/MAX6398 power up with the external FET in off mode (V GATE = GND). The external FET turns on t START after the
device is powered up and all input conditions are valid.
Note 3: For accurate overtemperature shutdown performance, place the device in close thermal contact with the external MOSFET.
Note 4: Dropout voltage is defined as V IN - V REG when V REG is 2% below the value of V REG for V IN = V REG (nominal) + 2V.
Note 5: Operations beyond the thermal dissipation limit may permanently damage the device.
