Built-in over-temperature shutdown and reverse polarity protection guard against common field faults: a shorted load that drives junction temperature above the die threshold triggers thermal foldback, and a reversed input supply does not damage the output pass element. ## DDPAK/TO-263-3 surface-mount package — thermal design note At 1.5 A output with 7 V input, the power dissipation is roughly 3 W — the board copper area and airflow determine the junction temperature, not the package alone.","metaTitle":"Texas Instruments UA7805CKTTR 5V 1.5A LDO, DDPAK/TO-263-3","metaDescription":"Texas Instruments UA7805CKTTR fixed 5V output LDO regulator, 1.5A, 2V dropout at 1A, PSRR 78dB~68dB at 120Hz.
