L7805 Voltage Regulator 5V - LM7805
VAT inclusive; Computed calculations added locally.
Overview
The L78M05CV 5V Linear Voltage Regulator IC is a three-terminal fixed positive voltage regulator designed to convert a higher DC input voltage into a stable 5V output. Its TO-220 package makes it convenient for through-hole PCB assembly, prototyping boards, and DIY electronics projects.
This L78M-series regulator supports an output current of up to 500mA and incorporates protective features such as thermal overload protection and output current limiting. It can be used to create localized 5V supply rails for microcontrollers, sensors, logic circuits, and other low-power electronic devices.
As a linear regulator, the voltage difference between the input and output is dissipated as heat. For applications involving high input voltages or substantial output current, appropriate thermal management such as a heatsink may therefore be necessary.

Important Notes
Because this is a linear regulator, power dissipation increases as the difference between input and output voltage increases. For example, converting a high input voltage to 5V at substantial current can generate significant heat. Use suitable thermal management where required.
The regulator requires sufficient input voltage above the regulated 5V output to maintain regulation. The provided specification lists a typical dropout headroom of approximately 2V.
The metal tab of the regulator package may be electrically connected to the regulator's ground depending on the specific package implementation. Check the relevant component documentation before mounting it directly to a conductive heatsink or chassis.
