Description
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.
These Plus to Minus ISRs incorporate
a “Buck-Boost” topology and are packaged
in the 3-pin, single in-line pin (SIP)
package configuration.
NOTE: PT5020 ISRs are not Short-Circuit Protected.

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.
