LDK220C-R Description

Short technical summary and product information.

The LDK220C-R from STMicroelectronics is a linear voltage regulator designed for adjustable positive output applications. It features a maximum output voltage of 13.2V and operates with a low quiescent current of 90µA. The device offers a voltage dropout of 0.35V at 200mA and includes protection features such as over current and over temperature.

 

This regulator is suitable for surface mount applications and comes in a compact SOT-323-5 package, also compatible with 5-TSSOP, SC-70-5, and SOT-353 formats. Its operating temperature range is from -40°C to 125°C, making it versatile for various environmental conditions. The LDK220C-R also provides good power supply ripple rejection (PSRR) between 60dB and 45dB across a frequency range of 120Hz to 10kHz.

 

With its adjustable output and enable control feature, the LDK220C-R is a flexible component for power management in electronic designs requiring stable and adjustable voltage regulation.
