This is the reflow-friendly version of the classic 7805—no through-hole pins, no separate heatsink bracket. Texas Instruments lists the part as Active, so it is a current-production choice for new designs, not a life-cycle buy. The ROHS3 compliance is standard for European and domestic builds. ## Dropout, PSRR, and protection thresholds Maximum dropout is 2V at 1A load. That means the input rail must stay at least 2V above 5V—7V minimum—under full load to keep the output in regulation. At lighter loads the dropout drops, but the 2V ceiling is the headroom to design for. The 80dB PSRR at 120Hz is the mains-ripple rejection figure—relevant if this regulator feeds an analog rail (op-amp supply, ADC reference) where 100/120Hz hum on the input would couple through. At 1.5A the quiescent current is 8 mA, which is low enough for most linear-regulator loads but not a low-Iq part for battery gear. Built-in over-temperature and short-circuit protection are standard 7805 features. The 35V input maximum is an absolute ceiling—do not exceed it even momentarily. Because the DDPAK package is less common than the through-hole TO-220, supply can be tighter on the surface-mount variant. We source directly from authorized distribution channels; every reel is traceable to a TI factory lot.

The difference is the package: LM7805SX/NOPB is surface-mount DDPAK/TO-263, while LM7805CT is through-hole TO-220. The pin functions are identical (input, ground, output, tab), but the PCB footprint and thermal management are completely different.
