I |
Enable input. A low voltage (< VIL) on this pin turns the regulator off and discharges the output pin to GND through an internal 230-Ω pulldown resistor. A high voltage (> VIH) on this pin enables the regulator output. This pin has an internal 1-MΩ pulldown resistor to hold the regulator off by default. |

Regulated output voltage. Connect a minimum 1-µF low-ESR capacitor to this pin. Connect this output to the load circuit. An internal 230-Ω (typical) pulldown resistor prevents a charge remaining on VOUT when the regulator is in the shutdown mode (VEN low). |
