NC = no internal connection.

at operating temperature range (T^J =–40°C to 125°C), VIN=VOUT(NOM) + 0.5V or 2.0V (whichever is greater), IOUT = 1mA, VEN = VIN, and CIN = COUT = 1μF (unless otherwise noted); all typical values at T^J = 25°C

over operating free-air temperature range (unless otherwise noted)(1)

(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2) The absolute maximum rating is VIN + 0.3 V or 6.0 V, whichever is smaller.

over operating free-air temperature range (unless otherwise noted)

(1) Make sure the nominal input and output capacitance is greater than 0.47μF. Throughout this document the nominal derating on these capacitors is 50%. Make sure the effective capacitance at the pin is greater than 0.47μF.
