The VRD1533MLX is a Linear Low Power Dropout Regulator, LLP-6, RoHS compliant, manufactured by AnaSem. It is a low-dropout, simple-to-use 3.3V regulator specifically designed for linear applications such as battery-powered devices, cellular phones, wireless network equipment, digital audio, set-top boxes, data communications, personal digital assistants (PDAs), and other low-power applications. It is optimized for use in low power, space constrained applications, has very low quiescent current of just 7uA maximum, and is extremely precise with +/-0.5% accuracy over line, load, and temperature changes. It utilises a 0.1uF output capacitor for stability, and supports normal presetting for output voltage of 1.8V to 3.3V. The package size is SOT23-5, which is ideal for board layout in many SMT/SMD applications.
