14 / 36 page  LT3045-1 14 30451fa For more information www.linear.com/LT3045-1 PIN FUNCTIONS GND (Pin 9, Exposed Pad Pin 13): Ground. The exposed backside is an electrical connection to GND. To ensure proper electrical and thermal performance, solder the exposed backside to the PCB ground and tie it directly to the GND pin. OUTS (Pin 10): Output Sense. This pin is the noninvert- ing 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 exists between OUTS and GND pins of the LT3045-1; do not drive OUTS more than 0.3V below GND during normal operation or during a fault condition. OUT (Pins 11, 12): Output. These pins supply 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 Informa- tion section for more information on output capacitance.
