PT6910 Series  
12 Watt 5V/3.3V Input  
Plus to Minus Voltage Converter  
SLTS113  
(Revised 11/30/2000)  
GaAs (-2.0V) ICs from an existing  
+5.0V or +3.3V source.  
Single-Device: +5V/3.3V input  
Remote Sense  
These regulators are similar to  
the popular PT6900 series with the  
added feature of Power Trends’ unique  
solderable copper case.  
+5V & +3.3V Input Voltage  
Adjustable Output Voltage  
23-pin Space-Saving Package  
Solderable Copper Case  
A 330µF electrolytic capacitor is  
required on both the input and output  
for proper operation. Also note that  
this product does not include short-  
circuit protection.  
The PT6910 series is a series of  
high performance 12 watt, plus to minus  
voltage convertors that are designed to  
power the latest ECL (–5.2V) and  
Patent pending on package assembly
