Pin-Out Information
GaAs (-2.0V) ICs from an existing
+5.0V or +3.3V source.
These regulators are similar to
the popular PT6900 series with the
added feature of Power Trends’ unique
solderable copper case.
A 330F electrolytic capacitor is
required on both the input and output
for proper operation. Also note that
this product does not include short-
circuit protection.

see Package Styles 1300 and 1310.)
