Electrical Characteristics (Extended Temperature Range)
Boldface limits apply for T
A =TJ =TMINto TMAX; all other limits TJ = 25C unless otherwise specified (SOT-23, see (Note
7)), I
RMIN ≤ IR ≤ 12 mA, VREF ≤ VOUT ≤ 10V. The grades C and D designate initial Reference Voltage Tolerances of ±0.5%
and ±1%, respectively for V
OUT = 5V.
