PT5020 Series  
Positive Input/Negative Output  
Integrated Switching Regulator  
SLTS025B  
(Revised 12/19/2001)  
Features  
Description  
• Negative Output  
• Input Voltage Range:  
+4.75 to +7 Volts  
The PT5020 series of integrated  
switching regulators (ISRs) convert a  
positive input voltage, typically +5V, to a  
negative output voltage for a wide range of  
analog and datacom applications.  
• Laser-Trimmed  
• Small Footprint  
• Soft Start  
These Plus to Minus ISRs incorporate  
a “Buck-Boost” topology and are packaged  
in the 3-pin, single in-line pin (SIP)  
package configuration.  
• 5-Pin Mount Option  
(Suffixes L & M)

Notes: (1) The ISR will operate at no load with reduced specifications.  
(2) For applications with input voltages greater than 7 VDC, use the PT78NR100 Series.  
(3) The inrush current stated is above the normal input current for the associated output load.  
(4) See Safe Operating Area curves or consult the factory for the appropriate derating  
(5) The tab pins on the 5-pin mount package types (suffixes L & M) must be soldered. For more information see the applicable package outline drawing.
