LDK320AM50R Description

Short technical summary and product information.

The STMicroelectronics LDK320AM50R is a linear voltage regulator belonging to the Voltage Regulators - Linear category. It operates with an input voltage of up to 18V and provides a fixed positive output. Key electrical characteristics include a low quiescent current of 90 µA and a voltage dropout of 0.35V at 200mA. Protection features such as over current and over temperature are integrated for enhanced reliability.

 

The device is supplied in a SOT-23-5 package, suitable for surface mount applications. It operates within a temperature range of -40°C to 125°C (TJ). The PSRR is rated between 88dB and 48dB across a frequency range of 120Hz to 10kHz.

 

This regulator is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1. Its compact SOT-23-5 package makes it ideal for space-constrained designs.
