Description
The LD39130S is a high accuracy voltage
regulator that provides 300 mA maximum current
from an input voltage ranging from 1.4 V to 5.5 V,
with a typical dropout voltage of 300 mV.
It is available in DFN6 1.2x1.3 mm package and
in ultra small CSP 4 bumps package, allowing the
maximum space saving.
The device is stabilized with a ceramic capacitor
on the output. The ultra low drop voltage, low
quiescent current and low noise features make it
suitable for low power battery-operated
applications. It integrates an internal logic
circuitry, which allows the regulator to be in ultra
low consumption mode (green mode), when the
output current required is very low. The normal
working mode, with fast transient response, is
restored when the load current increases.
The enable logic control function puts the
LD39130S in shutdown mode allowing a total
current consumption lower than 0.1 µA. The
current foldback and thermal protection are
provided.
