Pin Function
Supply Voltage (Input): Requires bypass capacitor-to-GND.
Enable (Input): Logic low will shut down the device, reducing the quiescent
current to less than 4µA.
Input to the error amplifier, connect to the external resistor divider network to set
the output voltage. For fixed output voltages connect to V
resistor network sets the output voltage.
Feed forward Capacitor connected to Out sense pin
Power Ground
Analog ground
Switch (Output): Internal power MOSFET output switches.
