*See Thermal Derating chart. **The PT6305 Series can be easily paralleled to provide output current in multiples of 3 amps. Please contact a Power Trends’ Application Engineer for the
appropriate application note. Note: The PT6305 Series requires a 100F electrolytic capacitor for proper operation in all applications.

The PT6305N is Power Trends’
new high performance +5V to +3.3V, 3
Amp, 12-Pin SIP (Single In-line-
Package) Integrated Switching
Regulator (ISR). This high-perfor-
mance ISR allows easy integration of
low-power 3.3V logic IC’s into existing
5V systems without redesigning the
central power supply. Only one external
capacitor is required for proper
operation. The PT6306,7,8 can be used
to power high-speed data buses (+2.1V),
or the new GTL (+1.2V) logic buses.
