Regarding the LP3878-ADJ datasheet section 7.4.1. It states:
7.4.1 Operation With VOUT(TARGET) + 2 V ≤ VIN ≤ 16 V
The device operates if the input voltage is equal to, or exceeds VOUT(TARGET) + 2 V. At input voltages below the
minimum VIN requirement, the device does not operate correctly and output voltage may not reach target value.
So if I want the output Voltage to be +3.3V it sounds like I need an input Voltage of +5.3V or greater.
Is this correct?
