The VRD1528MLX with Dropout Regulators (LDO) LLP-6 RoHS is a switch-mode power supply controller from Anasem. It has an input voltage range from 4.5V to 30V, and a wide output voltage range of 0.8V to 20V. It is RoHS compliant and provides short-circuit protection and temperature peaks, as well as over-voltage and under-voltage protection. Additionally, it has an active hysteresis voltage control, allowing for improved noise performance and internal dropout regulator LLP-6, which helps lower input voltage to a steady, low level. It is designed to support SMPS with digital circuits and wide voltage range, making it suitable for a variety of applications.
