Applications
disable state the device consumes as low as typ. 10 nA from the VIN.
If the EN pin voltage >0.9 V the device is guaranteed to be enabled. The NCV8114 regulates the output voltage and the active discharge transistor is turned -off.
The EN pin has internal pull -down current source with typ. value of 300 nA which assures that the device is turned -off when the EN pin is not connected. In the case where the EN function isn't required the EN should be tied directly to IN.
Pin Configuration
| Pin No. | Pin Name | Description |
|---|---|---|
| 5 | OUT | Regulated output voltage pin. A small ceramic capacitor with minimum value of 1 m F is needed from this pin to ground to assure stability. |
| 2 | GND | Power supply ground. |
| 3 | EN | Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode. |
| 1 | IN | Input pin. A small capacitor is needed from this pin to ground to assure stability. |
| 4 | N/C | Not connected. This pin can be tied to ground to improve thermal dissipation. |
