Pin Function
Output Pin: Connect to the output capacitor.
Supply (Input): 4.5V to 20V input voltage.
Internal regulated supply. VDD should be connected to VIN when VIN ≤ 7V.
Enable (Input): Logic high enables regulator. Logic low shuts down regulator.
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
Exposed backside pad for thermal cooling.
