Electrical Characteristics (continued)
Limits in standard typeface are for T J = 25°C, and limits in boldface type apply over the full operating temperature range.
Unless otherwise specified: VIN = VO(NOM) + 1V, IL = 1 mA, COUT = 4.7 µF, CIN = 2.2 µF, VS/D = 2V.

(6) Temperature coefficient is defined as the maximum (worst-case) change divided by the total temperature range.
(7) To prevent mis-operation, the Shutdown input must be driven by a signal that swings above VH and below VL with a slew rate not less
than 40 mV/µs (see Application Hints).
