LD6836 series

Ultra low dropout regulators, low noise, 300 mA

9.2 Dropout

The dropout voltage is defined as the smallest input to output voltage difference at a

specified load current when the regulator operates within its linear region. This means that

the input voltage is below the nominal output voltage value and the pass transistor works

as a plain resistor.

A small dropout voltage guarantees lower power consumption and efficiency

maximization.

9.3 Accuracy

The LD6836 series guarantees high accuracy of the nominal output voltage.
