MC79XX/MC79XXA/LM79XX
3-Terminal 1A Negative Voltage Regulator
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
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.
