WT78LXX  
Positive Voltage Regulator  
P b  
Lead(Pb)-Free  
General Description:  
The WT78LXX series of positive regulators are available in the SOP-8 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. WT78LXX is characterized for operation from 0°C to  
+125°C.  
Features:  
* Internal Short-Circuit Current Limiting.  
* Internal Thermal Overload Protection.  
* No External Components Required.
