SNVS159H – OCTOBER 2001 – REVISED JULY 2015
8.4 Device Functional Modes
8.4.1 Operation with VOUT(TARGET) + 0.3 V ≤ VIN ≤ 6 V
The device operate if the input voltage is equal to, or exceeds VOUT(TARGET) + 0.3 V. At input voltages below the
minimum VIN requirement, the devices do not operate correctly and output voltage may not reach target value.
8.4.2 Operation With EN Control
If the voltage on the EN pin is less than 0.4 V, the device is disabled, and in this state the shutdown current does
not exceed 1.5
μA. Raising EN above 1.4 V initiates the start-up sequence of the device.
