Overview of LDK220U50R by STMicroelectronics
The LDK220U50R, manufactured by STMicroelectronics, is a low dropout (LDO) linear regulator designed to deliver a maximum output current of 200 mA with an output voltage of 5V. Encased in a small outline SOT89 package, this component offers a commendably low dropout voltage of approximately 1V and operates with input voltages ranging from 6V to a maximum of 13.2V. Its compact form factor (4.5 mm length, 2.445 mm width, and a seated height of only 1.6 mm) and plastic/epoxy package material make it versatile for dense circuit layouts.
The LDK220U50R possesses several significant attributes reinforcing its quality and reliability. It features a maximum load regulation of 0.02985% and tolerates a voltage fluctuation of up to 3%. Moreover, it is designed to operate over a broad temperature range from -40 °C to 125 °C, ensuring functionality under extreme conditions. Being RoHS compliant and Reach compliant underscores its adherence to environmental and health standards. These attributes make it a suitable choice for applications demanding stable voltage in compact, high-temperature environments.
