Description

General part information

LDK320 Series

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.
