Applications
The LM7805MPX/NOPB provides a regulated 5 V supply rail in embedded systems, microcontroller boards, and consumer electronics that operate from unregulated 9 V to 24 V DC power adapters or transformer-rectifier supplies. Its wide 7.5 V to 30 V input range makes it compatible with a broad set of unregulated input sources, including wall warts, industrial 24 V bus rails, and battery strings. The SOT-223 surface-mount package suits modern PCB designs that need through-hole LDO performance in a compact, wave-solderable form factor.

Frequently Asked Questions
What input voltage range does LM7805MPX/NOPB support and what is its absolute maximum?
The LM7805MPX/NOPB operates from 7.5 V minimum to 30 V maximum input voltage, with an absolute maximum rating of 35 V. This 35 V ceiling provides a comfortable margin for transient spikes on unregulated power supplies, preventing device damage when used with capacitor-filtered rectifier inputs that can momentarily exceed the nominal supply.
How does the SOT-223 package of LM7805MPX/NOPB compare to a TO-220 for modern PCB assembly?
The 4-pin SOT-223 (R-PDSO-G4) is a surface-mount package measuring approximately 6.5 mm x 3.5 mm, eliminating through-hole drilling and enabling automated pick-and-place assembly. Compared to a TO-220 through-hole package, SOT-223 reduces PCB footprint by roughly 50% and allows placement on the bottom side of the board, simplifying single-side PCB routing in compact 5 V regulator applications.
For a 12 V to 5 V conversion at 500 mA, how much power does LM7805MPX/NOPB dissipate and what thermal consideration applies?
At 12 V input and 5 V output with 500 mA load current, the LM7805MPX/NOPB dissipates (12 V - 5 V) x 0.5 A = 3.5 W. The SOT-223 package has a thermal resistance of approximately 50°C/W junction-to-board with adequate copper pour, so a 3.5 W dissipation raises junction temperature roughly 175°C above ambient without heatsinking — requiring a copper thermal pad on the PCB or derating the load current.
Is LM7805MPX/NOPB suitable for designs with decade-long production runs?
Yes. The LM7805MPX/NOPB carries a YTEOL rating of 15 years, one of the longest availability commitments in TI's linear regulator portfolio. Combined with the 2016 production introduction date, this supports industrial equipment, infrastructure hardware, and instrumentation products that require stable component sourcing well into the 2030s without costly redesigns.
