ST LDK320M33R

Позитив18V200 мА

Overview

The LDK320M33R 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 LDK320M33R 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.
