LM78XX (KA78XX, MC78XX) FIXED VOLTAGE REGULATOR (POSITIVE)
3-TERMINAL 1A POSITIVE
VOLTAGE REGULATORS
The LM78XX series of three-terminal positive regulators are 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 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.
