LDK320M25R Description

Short technical summary and product information.

The LDK320M25R from STMicroelectronics is a linear voltage regulator designed for various power management applications. It provides a stable, fixed output voltage of 2.5V and can deliver up to 200mA of current.

 

Key electrical specifications include a maximum input voltage of 18V and a low quiescent current of 90 µA, making it suitable for power-sensitive designs. The device also features a maximum supply current of 100 µA and offers a Power Supply Rejection Ratio (PSRR) ranging from 83dB to 58dB across a frequency range of 120Hz to 10kHz.

 

This regulator operates within a wide temperature range of -40°C to 125°C (TJ). It is housed in a compact SOT-23-5 package, also referred to as SC-74A or SOT-753, and is designed for surface mount applications. Protection features include over-current and over-temperature capabilities, with an enable control feature for added flexibility.

 

The LDK320M25R is packaged in tape and reel, suitable for automated assembly processes. Its robust design and specifications make it a reliable choice for applications requiring a consistent and regulated power supply.
