pin FuncTions

OUTS (Pin 9/Pin 10): Output Sense. This pin is the non-

inverting input to the error amplifier. For optimal transient

performance and load regulation, Kelvin connect OUTS

directly to the output capacitor and the load. Also, tie the

GND connections of the output capacitor and the SET pin

capacitor directly together. A parasitic substrate diode ex-

ists between OUTS and GND pins of the LT3045; do not

drive OUTS more than 0.3V below GND during normal

operation or during a fault condition.

OUT (Pin 10/Pins 11, 12): Output. This pin supplies

power to the load. For stability, use a minimum 10µF

output capacitor with an ESR below 20mΩ and an ESL

below 2nH. Large load transients require larger output

capacitance to limit peak voltage transients. Refer to the

Applications Information section for more information

on output capacitance. A parasitic substrate diode exists

between OUT and GND pins of the LT3045; do not drive

OUT more than 0.3V below GND during normal operation

or during a fault condition.
