Pin Function
Switch (Output): Internal power P-Channel MOSFET output switch.
Supply Voltage (Input): Supply voltage for the source of the internal P-channel MOSFET and driver.
Requires bypass capacitor to GND.
Power Ground. Provides the ground return path for the high-side drive current.
Signal (Analog) Ground. Provides return path for control circuitry and internal reference.
Internal circuit bias supply. Must be bypassed with a 0.1μF ceramic capacitor to SGND.
Feedback. Input to the error amplifier, connect to the external resistor divider network to set the
output voltage.
No Connect. Not internally connected to die. This pin can be tied to any other pin if desired.
Enable (Input). Logic level low, will shutdown the device, reducing the current draw to less than 5μA.
Power Good. Open drain output that is pulled to ground when the output voltage is within ±7.5% of
the set regulation voltage.
Connect to ground.
