LM7805 Datasheet – Positive 5V Regulator

LM7805 is 3-terminal 1A, 5V Voltage Regulator.

Part number : LM7805


Package information : TO-220 Plastic Type

Manufacturer : UTC, Fairchild, Continental Device India Limited


LM7805 transistor regulator


The LM7805 of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

The LM78XX offer several fixed output voltages making them useful in wide range of applications. When used as a zener diode/resistor combination replacement, the LM78XX usually results in an effective output impedance improvement of two orders of magnitude, lower quiescent current.



1. Output current up to 1A
2. Fixed output voltage of 5V
3. Thermal overload shutdown protection
4. Output transistor SOA protection
