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 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.

(For dimensions and PC board layout,

see Package Styles 1300 and 1310.)
