PinNameFunctionSource
1IN, Input voltage supply. Connect a 1μF capacitor at this input.
2GND, Common ground.
3EN, Enable input. A low voltage (<VIL) on this pin turns the regulator off and discharges the output pin to GND through an internal 230Ω pulldown resistor. A high voltage (>VIH) on this pin enables the regulator output. This pin has an internal 1MΩ pulldown resistor to hold the regulator off by defa
4N/C, No internal electrical connection.
5OUT, Regulated output voltage. Connect a minimum 1μF low-ESR capacitor to this pin. Connect this output to the load circuit. An internal 230Ω (typical) pulldown resistor prevents a charge remaining on VOUT when the regulator is in shutdown mode (VEN low).
