The HT7530-3 is a Low Dropout Regulator (LDO) from Holtek that comes in an SOT-89 package. This device is designed specifically for use in high-end, noise sensitive applications, and is RoHS compliant. The main features of the HT7530-3 include: a max operating voltage of 6.5V, a max output current of 500mA, a max dropout voltage of 0.35V, a minimum quiescent current of 0.6mA, and very low noise. The output voltage of the HT7530-3 can be adjusted by a single resistor, and short-circuit protection is included. It also features low power dissipation, over-temperature protection; and low output voltage drift. The HT7530-3 is ideally suited for applications like digital-analog converters, battery-powered products, and power supplies.
