LDK320AM25R Description

Short technical summary and product information.

The STMicroelectronics LDK320AM25R is a single-output positive linear voltage regulator designed for various electronic applications. It provides a stable 2.5V output voltage with a maximum output current of 200mA. The device features a low quiescent current of 90 µA, making it suitable for power-sensitive designs.

 

Key electrical characteristics include a voltage dropout of 0.35V at 200mA and a PSRR of 88dB to 48dB across a frequency range of 120Hz to 10kHz. Protection features such as over current and over temperature are integrated to enhance reliability. The regulator operates within a junction temperature range of -40°C to 125°C.

 

Packaged in a SOT-23-5 (SC-74A, SOT-753) surface-mount case, the LDK320AM25R is designed for easy integration into printed circuit boards. Its fixed output and enable control feature simplify circuit design.
