LDK320 Overview
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, bined with low drop voltage and low quiescent current make it suitable for low power battery-powered applications.
