LP5907MFX-3.3/NOPB Applications
LP5907MFX-3.3/NOPB Pin Configuration
| Pin | Name | Type | Description |
|---|---|---|---|
| 1 | IN | I | Input voltage supply. Connect a 1µF capacitor at this input. |
| 2 | GND | - | Common ground. |
| 3 | EN | I | 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 default. |
| 4 | N/C | - | No internal electrical connection. |
| 5 | OUT | O | 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). |

LP5907MFX-3.3/NOPB Typical Application
The LP5907 is designed to meet the requirements of RF and analog circuits, by providing low noise, high PSRR, low quiescent current, and low line or load transient response figures. The device offers excellent noise performance without the need for a noise bypass capacitor and is stable with input and output capacitors with a value of 1μF.
