Pin Function
Supply (Input): 4.5V to 20V input voltage.
Internal regulator. VDD should be connected to VIN when VIN ≤ 7V.
Enable (Input): Logic high enables regulator. Logic low shuts down regulator.
Analog Ground
Soft Start
Feedback (Input): 1.25V output voltage sense node. V_OUT = 1.25V ( 1 + R1/R2)
Switch Node (Input): Internal power BIPOLAR collector.
Power ground
Ground (Return): Exposed backside pad. Internally fused to AGND and PGND
pins.
