LM78XX (KA78XX, MC78XX) FIXED VOLTAGE REGULATOR (POSITIVE) 3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS TO-220 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.
