Overview of LDK320ADU33R

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.

Key Features
