(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Recommended Operating Conditions are
conditions under which the device functions but the specifications might not be ensured. For ensured specifications and test conditions
see the Electrical Characteristics (5 V and 8 V).
(2) 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, T
J
, the junction-to-ambient thermal
resistance, R
θJA
, and the ambient temperature, T
A
. Exceeding the maximum allowable power dissipation will cause excessive die
temperature, and the regulator will go into thermal shutdown. The value of R
θJA
(for devices in still air with no heatsink) is 23.3°C/W for
the TO-220 package, 40.9°C/W for the DDPAK/TO-263 package, and 59.3°C/W for the SOT-223 package. The effective value of R
θJA
can be reduced by using a heatsink (see Heatsinking for specific information on heatsinking). The value of R
θJA
for the WSON package
is specifically dependent on PCB trace area, trace material, and the number of layers and thermal vias. For improved thermal resistance
and power dissipation for the WSON package, refer to Application Note AN-1187 Leadless Leadframe Package (LLP) (SNOA401). It is
recommended that 6 vias be placed under the center pad to improve thermal performance.
(4) Refer to JEDEC J-STD-020C for surface mount device (SMD) package reflow profiles and conditions. Unless otherwise stated, the
temperature and time are for Sn-Pb (STD) only.
6.2 ESD Ratings
