LDK220M50R Description

Short technical summary and product information.

The STMicroelectronics LDK220M50R is a linear voltage regulator designed for power management applications. It offers a fixed 5V output voltage and can supply a maximum current of 200mA. The device features a low dropout voltage of 0.35V at 200mA and operates over a wide temperature range from -40°C to 125°C.

 

This regulator includes over-current and over-temperature protection features, along with an enable control input. It is housed in a compact SOT-23-5 (SC-74A) surface-mount package, making it suitable for space-constrained designs. The LDK220M50R is ideal for various electronic circuits requiring a stable and reliable voltage supply.

 

Key electrical characteristics include a quiescent current of 90 µA and a supply current of 100 µA. The PSRR is rated between 55dB and 50dB across a frequency range of 120Hz to 10kHz. Its input voltage can be as high as 13.2V.
