7.4 Device Functional Modes

7.4.1 Enable (EN)

The LP5907-Q1 Enable (EN) pin is internally held low by a 1-MΩ resistor to GND. The EN pin voltage must be

higher than the VIH threshold to ensure that the device is fully enabled under all operating conditions.

When the EN pin is pulled low, and the output is disabled, the output automatic discharge circuitry is activated.

Any charge on the OUT pin is discharged to GND through the internal 230-Ω (typical) pull-down resistance.

7.4.2 Minimum Operating Input Voltage (VIN)

The LP5907-Q1 does not include any dedicated undervoltage lockout circuitry. The LP5907-Q1 internal circuitry

is not fully functional until VIN is at least 2.2 V. The output voltage is not regulated until VIN has reached at least

the greater of 2.2 V or (VOUT + VDO).
