  • LP5900: Regulation at dropout voltage less than 1 V

    Resolved
    Part Number: LP5900 The datasheet says that at least 1 V dropout voltage is required for achieving good regulation, however the minimum dropout voltage is a lot less. How bad the regulation will be with let's say Vin=Vout + 0.5V? Thanks.
