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.
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.
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.
Power Ground. Provides the ground return path for the high-side drive current.
