Description
The LD39030 high accuracy voltage regulator
provides 300 mA of maximum current from an
input voltage ranging from 1.5 V to 5.5 V, with a
typical dropout voltage of 300 mV.
It is available in DFN4 1x1 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,
together with the internal soft-start circuit, make
the LD39030 suitable for low power battery-
operated applications.
An enable logic control function puts the
LD39030 in shutdown mode allowing a total
current consumption lower than 0.1 µA. Constant
current and thermal protection are provided.
