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
