MC7912A Datasheet | Fairchild Semiconductor

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 pensation Description 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. TO-220 Vin 1. GND 2. Input 3.
