Pin-compatible alternative with higher current, but a narrower temperature range.
Best Alternatives to L7805CV(UMW)
The UMW L7805CV is a popular 5V, 1.2A linear voltage regulator in a TO-220 package. Finding a suitable replacement involves matching the package, pinout, and key electrical ratings like input voltage and output current.
AI replacement insight
Package riskhigh
Many alternatives are surface-mount and require a new PCB layout.
Electrical riskmedium
Check temperature range, input voltage, and output current ratings carefully.
Can it be replaced directly?
Direct replacement for L7805CV(UMW) should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For a near drop-in, use L7805CV-DG but verify the 0°C minimum temperature. For new designs, L7805ABD2T-TR is an excellent surface-mount option.
Main risk
The main risk is overlooking the operating temperature range or selecting a part with a different package that requires a board redesign.
