(1) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ_MAX, the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD_MAX = (TJ_MAX - TA) /θJA. The maximum power dissipation of 2.6W is determined using TA = 25°C, θJA = 38°C/W, and TJ_MAX = 125°C. The number stated here reflects the maximum power dissipation for the package and not the device.

(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications.

(3) For Device Power Dissipation, please refer to section 10.3.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended Operating Conditions indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics.

(2) Below 4.0-V input, power dissipation may increase due to increased R_DS(ON). Therefore, a minimum input voltage of 4.0 V is required to operate continuously within specification. A minimum of 3.9 V (typical) is also required for startup.

(3) All room temperature limits are 100% production tested. All limits at temperature extremes are ensured through correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

(4) Iq and ISD specify the current into the VIN pin. IBIAS is the current into the VBIAS pin when the VBIAS voltage is greater than 3 V. All quiescent current specifications apply to non-switching operation.

(5) The absolute maximum specification applies to DC voltage. An extended negative voltage limit of -2V applies for a pulse of up to 1 µs, and –1 V for a pulse of up to 20 µs.
