LDK320AM36R Description

Short technical summary and product information.

The STMicroelectronics LDK320AM36R is a linear voltage regulator designed for various power management applications. It provides a fixed positive output voltage and is suitable for circuits requiring precise voltage regulation.

 

Key electrical specifications include an operating voltage of 18V and a low quiescent current of 90µA. The dropout voltage is a maximum of 0.35V at 200mA, and it features over-current and over-temperature protection. The PSRR is rated between 88dB and 48dB across a frequency range of 120Hz to 10kHz.

 

This device operates within a temperature range of -40°C to 125°C (TJ). It is available in a SOT-23-5 package, also referred to as SC-74A or SOT-753, and utilizes surface mount technology for integration into PCBs.

 

The LDK320AM36R includes an Enable control feature for power management. It is RoHS3 compliant, has an MSL of 1, and is REACH unaffected, though these compliance statuses are unverified.
