Product Summary

The LM7805 is a three terminal positive regulator. The LM7805 is available in the TO-220/D-PAK 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, the LM7805 can be used with external components to obtain adjustable voltages and currents.

Parametrics

LM7805 absolute maximum ratings: (1)Input Voltage (for VO= 5V to 18V), VI: 35V; (for VO = 24V), VI: 40V; (2)Thermal Resistance Junction-Cases (TO-220), RθJC: 5℃/W; (3)Thermal Resistance Junction-Air (TO-220), RθJA: 65℃/W; (4)Operating Temperature Range, TOPR: 0 to +125℃; (5)Storage Temperature Range, TSTG: -65 to +150℃.

Features

LM7805 features: (1)Output Current up to 1A; (2)Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V; (3)Thermal Overload Protection; (4)Short Circuit Protection; (5)Output Transistor Safe Operating Area Protection.
