DESCRIPTION
The PT6400 is a high performance +5V to +3.3V, 3 Amp, 12 Pin SIP (Single In line Package) Integrated Switching Regulator
(ISR) designed for stand alone (not parallelable) operation. This high performance ISR allows easy integration of low power
3.3V logic IC’s into existing 5V systems without redesigning the central power supply. Only two external capacitors are
required for proper operation. The output voltage is easily adjustable with one external resistor. The PT6406,7,8 can be used
to terminate high speed data buses such as Futurebus (+2.1V) or the new GTL (+1.2V) logic buses.
Please note that this product does not include short circuit protection.
