Fairchild Semiconductor MC7912
The MC79XX / MC79XXA/ LM79XX series of three terminal negative regulators are available in 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.FEATURES
● Output Current in Excess of 1A● Output Voltages of -5, -6, -8 , -9, -10, -12, -15, -18 and 24V
● Internal Thermal Overload Protection
● Short Circuit Protection
● Output Transistor Safe Operating Area Compensation
