Application Information
VIN (PIN1): Power Input for REG1. Bypass to GND with a high quality ceramic capacitor placed as
close as possible to the REG1.
SW (PIN2): Switching node Output for REG1. Connect this pin to the switching end of the inductor.
GND (PIN3): Power Ground, as close to the IC as possible.
VOUT2 (PIN4): Output voltage for REG2, capable of delivering up to 300mA of output current.
FB2 (PIN5): Output Feedback Sense. Receives the feedback voltage from an external resistive divider
across the output. The output voltage for REG1 is set by a resistive divider according to the following
formula: VOUT2 = 1.212V • [1 + (R3/R4)].
VINL (PIN6): Power input for REG2, REG3. Bypass to GND with a high quality ceramic capacitor placed
as close as possible to the IC.
VOUT3 (PIN7): Output voltage for REG3, capable of delivering up to 300mA of output current.
FB3 (PIN8): Output Feedback Sense. Receives the feedback voltage from an external resistive divider
across the output. The output voltage for REG3 is set by a resistive divider according to the following
