Question of LM27762

Hi Nishizawa-san,

With 5Vin, you will not get -5Vout. It will be lower by the output impedance and LDO dropout.

Many applications do not need -5.0Vout. If you do, you need to use an inverting buck-boost converter circuit such as this reference design: http://www.ti.com/tool/PMP9760
