LM27762: Line and load regulation at 3V and 2.7V

Part Number: LM27762

Tool/software:

Dear e2e Support,

Do we have similar graph than the datasheet figure 5 to 8, with an input voltage of 2.7V and 3V? and ideally for a +/-5Vout.

Regards,

    Hello,

    thanks for using E2E.

    It is impossible to generate a Vout of +/- 3.3V or +/-5V from an input voltage of 2.7V and 3V. The abs value of the output voltage will always be smaller than the input voltage. (The positive output has some voltage drop across the LDO. The negative output is generated from the inverted VIN and is then also reduced by the LDO voltage drop.)

    Best regards,

    Andreas.
