Description
Maturity status link
LD59030
The
LD59030
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
135 mV at V
OUT
= 3.3 V.
It is available in DFN4 1x1 package, allowing the maximum space saving.
The device works 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 and output current fold-back protection, make the
LD59030
suitable for low
power battery-operated applications.
An enable logic control function puts the
LD59030
in shutdown mode allowing a total
current consumption lower than 0.03 µA.
