Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the

device is intended to be functional, but device parameter specifications may not be ensured. For ensured specifications and test

conditions, see the Electrical Characteristics.

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

specifications.

(3)

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. See the Electrical Characteristics table for the thermal resistance. The maximum

allowable power dissipation at any ambient temperature is calculated using: PD (MAX) = (TJ(MAX) − TA)/θJA. Exceeding the maximum

allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.

(4)

The human body model is a 100 pF capacitor discharged through a 1.5k

Ω resistor into each pin.

All limits specified at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are

100% tested or ensured through statistical analysis. All limits at temperature extremes are specified via correlation using standard

Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

Electrical Characteristics

Specifications in standard type face are for TJ = 25°C and those with boldface type apply over the full Operating

Temperature Range (TJ = −40°C to +125°C). VIN = 5V, IL = 0A, and FSW = 300kHz unless otherwise specified.
