Description
The LM79LXXM3 series of negative regulators are available in the SOT-89 package and with -5V, -6V, -8V,-9V,
-12V, -15V, -18V and -24V fixed output voltages, making it useful in a wide range of applications. These regulators
can provide local on-card regulation, eliminating the distribution problems associated with single point regulation.
Each type employs internal current limiting, thermal shut-down and safe operating area protection, making it
essentially indestructible. If adequate heat sinking is provided, they can deliver over 100mA output current.
Although designed primarily as fixed voltage regulators, these devices can be used with external components to
obtain adjustable voltages and currents. LM79LXXM3 is characterized for operation from 0℃ to 125℃.
Features:
• Internal Short-Circuit Current Limiting
• Internal Thermal Overload Protection
• No External Components Required
• Pb-free lead plating package

A common ground is required between the
input and the output voltages. The input
voltage must remain typically 2.0V above
the output voltage even during the low point
on the input ripple voltage.
Note : C1 and C2 are required if regulator is located
far from power supply filter and load, or oscillation
may induced on the loop.
