LDK220U50R Description

Short technical summary and product information.

The LDK220U50R from STMicroelectronics is a linear voltage regulator designed to provide a stable 5V output voltage with a maximum current capability of 200mA. It features a low dropout voltage of 0.35V at 200mA and a quiescent current of 90µA, making it suitable for power-sensitive applications.

 

This device operates within a temperature range of -40°C to 125°C (TJ) and includes protection features such as over current and over temperature shutdown. The regulator has a PSRR of 55dB to 50dB across a frequency range of 120Hz to 10kHz, aiding in noise reduction.

 

Packaged in a TO-243AA (SOT-89) case, the LDK220U50R is designed for surface mounting. Its positive output configuration and enable control feature make it a versatile component for various electronic designs requiring a reliable and protected linear voltage regulation.

 

Compliance information indicates RoHS3 compliance, MSL 1, and REACH unaffected status, though these are noted with low confidence due to lack of direct verification.
