FUNCTION
Inductor Connection 1. Connect an inductor between LX1 and OUT1.
Analog Supply Voltage. Bypass with 0.1μF to ground.
OUT1 Regulator Compensation. Connect series RC network from COMP1 to GND.
3
COMP1
COMP1
COMP1 is pulled to GND when the outputs are shut down. See the Compensation
Design section for component values.
OUT1 Feedback. Connected to OUT1 for internal mode (FBSEL1 = GND or V CC ).
4
FB1
FB1
Use an external resistor-divider from OUT1 to GND to set the output voltage from
1.2V to V IN for external mode (FBSEL1 = unconnected). See the Output Voltage
Selection section for <1.2V output.
OUT2 Feedback. Connected to OUT2 for internal mode (FBSEL2 = GND or V CC ).
5
FB2
FB2
Use an external resistor-divider from OUT2 to GND to set the output voltage from
1.2V to V IN for external mode (FBSEL2 = unconnected). See the Output Voltage
Selection section for <1.2V output.
OUT2 Regulator Compensation. Connect series RC network from COMP2 to GND.

COMP2
COMP2
COMP2 is pulled to GND when the outputs are shut down. See the Compensation
Design section for component values.
