5 / 26 page LP2986 www.ti.com SNVS137H – MARCH 1999 – REVISED APRIL 2013 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).
