1) _{Measured when the output voltage VQ has dropped 100 mV from the nominal value obtained at VI = 13.5 V.}
Note: The listed characteristics are ensured over the operating range of the integrated
circuit. Typical characteristics specify mean values expected over the production
spread. If not otherwise specified, typical characteristics apply at T_a = 25 °C and
the given supply voltage.
