Description
The LDK320 is a low drop voltage regulator,
which provides a maximum output current of
200 mA from an input voltage in the range of
2.5 V to 18 V, with a typical dropout voltage of
100 mV.
It is stabilized with a ceramic capacitor on the
output.
The very good dynamic characteristic, combined
with low drop voltage and low quiescent current
make it suitable for low power battery-powered
applications.
The enable logic control function allows the
LDK320 to be in shutdown mode by consuming a
total current lower than 1 μA.
This device also includes a short-circuit current
limiting, thermal and SOA protections.
