The HT7333-A is a series of low-dropout (LDO) linear voltage regulators manufactured by Guoxin Jiapin Semiconductor, commonly found in SOT-89 packages. They are designed to supply a constant voltage output from a wide range of inputs, with maximum operating temperatures of up to 125°C. These devices have an extended operating temperature range and feature both protection from short circuit and over-temperature conditions. With their low quiescent current consumption, the HT7333-A series offers high accuracy and a low dropout of only 80mV compared to other devices. Additionally, the parts are RoHS compliant, making them an environmentally conscious choice.
