3 AMP HIGH-PERFORMANCE

ADJUSTABLE ISR

• Single-Device 5V to 3V Power

• 85% Efficiency

Amp, 12-Pin SIP (Single In-line-

Package) Integrated Switching

• Small SIP Footprint:

0.36" x 2.00” x 0.60"(H)

• Wide Input Voltage Range:

+4.5V to +9.0V

• Internal Short Circuit Protection

• Over-Temperature Protection

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.

The PT6305N is Power Trends’

new high performance +5V to +3.3V, 3

*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 100µF electrolytic capacitor for proper operation in all applications.

Note 1: All data listed in the above graphs, except for derating data, has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.

Note 2: Minimum V_indata is typical and is not guaranteed. The data corresponds to a 2% output voltage drop.

Note 3: Thermal derating graphs are developed in free air convection cooling of 40-60 LFM with no optional heat tab soldered in a printed circuit board. (See Thermal Application Notes).
