These are stress ratings only and functional operation of the device at
these ratings or any other above those indicated in the operation sections
of the specifications below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect reliability.
ELECTRICAL CHARACTERISTICS
VIN = 13.5V; -40°C < TJ < 125°C. The ♦ denotes the specifications which apply over the full operating temperature range, unless
otherwise specified.

Note 1: Specifications in the -40°C to 150°C range are guaranteed by design, not production tested.
Note 2: Drop voltage = VI - VQ measured when the output voltage has dropped 100mV from the nominal value obtained at 13.5V input.
Note 3: The reset threshold VRT can be decreased via an external voltage divider connected to the RADJ. In this case the reset condition is reached if
VQ < VRT and VRADJ < VRAQDJ, TH . Dimensioning the voltage divider according to: VTHRES = VRADJ, TH X (RADJ1 +RADJ2 )/RADJ2.
