LM7812 Vs LM7805 Key Differences
LM7812 Vs LM7805 Price
The price of LM7812 and LM7805 can vary depending on the retailer, quantity purchased, and other factors.
However, in general, LM7812 tends to be slightly more expensive than LM7805. Here's a rough comparison:
LM7812: $1.50 - $2.50
LM7805: $1.00 - $2.00
LM7812 Vs LM7805 Package
The LM7812 and LM7805 come in different package types. The LM7812 typically comes in a TO-220 package, while the LM7805 typically comes in a TO-220 or SOT-223 package. The TO-220 package is a metal can package, while the SOT-223 package is a surface-mount package.

LM7812 vs LM7805: Differences
The LM7812 and LM7805 are two popular linear voltage regulator ICs manufactured by National Semiconductor. They are both used to provide a stable voltage output for electronic circuits, but there are some key differences between them.
LM7812 vs LM7805 Output Voltage
The most noticeable difference between the LM7812 ic and LM7805 ic is their output voltage. The LM7812 provides a fixed output voltage of 12V, while the LM7805 provides a fixed output voltage of 5V. This makes the LM7812 suitable for applications that require a higher voltage, while the LM7805 is suitable for applications that require a lower voltage.
LM7812 vs LM7805 Maximum Output Current
Another difference between the LM7812 and LM7805 is their maximum output current. The LM7812 has a maximum output current of 1.5A, while the LM7805 has a maximum output current of 1A. This means that the LM7812 can provide more current to a load, making it more suitable for high-current applications.
