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

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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS
&
no Sb/Br)
-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
