Feature Description (continued)

7.3.7 Enhanced Stability

The LP2985LV-N is designed specifically to work with ceramic output capacitors, utilizing circuitry which allows

the regulator to be stable across the entire range of output current with an output capacitor whose ESR is as low

as 5 mΩ. For output capacitor requirement, refer to Output Capacitor.

7.3.8 Low Noise

The LP2985LV-N includes a low-noise reference ensuring minimal noise during operation because the internal

reference is normally the dominant term in noise analysis. Further noise reduction can be achieved by adding an

external bypass bapacitor between the BYPASS pin and the GND pin.

7.4 Device Functional Modes

7.4.1 Operation with VOUT(TARGET) + 0.6 V ≥ VIN > 16 V

The device operate if the input voltage is equal to, or exceeds VOUT(TARGET) + 0.6 V. At input voltages below the

minimum VIN requirement, the devices do not operate correctly and output voltage may not reach target value.

7.4.2 Operation With ON/OFF Control

If the voltage on the ON/OFF pin is less than 0.15 V, the device is disabled, and in this state shutdown current

does not exceed 2 μA. Raising ON/OFF above 1.6 V initiates the start-up sequence of the device.
