5 / 14 page 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. Un- less otherwise specified: V IN =VO(NOM) + 1V, IL = 1 mA, COUT = 4.7 µF, CIN = 2.2 µF, VS/D = 2V.

Electrical specifications do not apply when operating the de- vice outside of its rated operating conditions. Note 2: The ESD rating of the Feedback pin is 500V and the Tap pin is 1.5 kV. Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, θJ−A, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: The value of θJ−A for the SO-8 (M) package is 160˚C/W, and the mini SO-8 (MM) package is 200˚C/W. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Note 4: If used in a dual-supply system where the regulator load is returned to a negative supply, the LM2986 output must be diode-clamped to ground. Note 5: The output PNP structure contains a diode between the V IN and VOUT terminals that is normally reverse-biased. Forcing the output above the input will turn on this diode and may induce a latch-up mode which can damage the part (see Application Hints). Note 6: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL). Note 7: Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a 1V differential. Note 8: 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). Note 9: Temperature coefficient is defined as the maximum (worst-case) change divided by the total temperature range. Note 10: VFB ≤ VOUT ≤ (VIN − 1), 2.5V ≤ VIN ≤ 16V, 100 µA ≤ IL ≤ 200 mA, TJ ≤ 125˚C. Note 11: See Typical Performance Characteristics curves. www.national.com 5 |
