TLV758P: Vdo value of TLV757 / TLV758

Hi Yokota,

Dropout for linear regulators has a linear relationship with Iout.  As such we can calculate the dropout using a simple ratio and the data provided in the Electrical Characteristics table.  Below I will demonstrate with TLV758P

For a 1 V output at 500 mA we see that the maximum dropout is 570 mV.

Vdo_300 mA / 300 mA = Vdo_500 mA / 500 mA

Vdo_300 mA / 300 mA =570 mV / 500 mA

Vdo_300 mA / 300 mA = 1.14 mV / mA

Vdo_300 mA = 1.14 mV / mA  x 300 mA 

Vdo_300 mA = 342 mV

Our calculated maximum dropout for a 1 V output for TLV758P at 300 mA is 342 mV.

Very Respectfully,

Ryan
