Description
SOT-23
The LM78LXXN3 series of positive regulators are available in the SOT-23 package and with 5V, 6V, 8V, 9V, 10V,
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. LM78LXXN3 is characterized for operation from 0to 125.
Features:
Internal Short-Circuit Current Limiting
Internal Thermal Overload Protection
No External Components Required
Pb-free lead plating and halogen-free package
