The SE5220-LF-ADJ is a low dropout regulator (LDO) SOT23-5 RoHS manufactured by Seaward. It is an adjustable, low-dropout linear voltage regulator, offering an output voltage range of as low as 1.8V up to 5.2V, with a maximum output current of 500mA. It provides excellent accuracy (±1%), load and line regulation (±0.2%), and low-noise performance. This LDO offers excellent transient response, fast startup time, and reverse battery protection. It also includes overcurrent protection and thermal shutdown, ensuring safe operation and system reliability. The SE5220-LF-ADJ can operate over the ambient temperature range of -40 °C to +85°C, with no need for external components. It is RoHS compliant and provides a small footprint for space-constrained applications.
