The HT7333 is a SOT-23 Linear Voltage Regulator (LDO) ROHS manufactured by GUOXIN JIAPIN SEMICONDUCTOR. It is a low drop-out voltage regulator that gives a fast and stable response over changes in temperature and load. It uses a 5V input to regulate an output voltage of 3.3V with a 0.1V exactness, while offering low noise, frequency response, low consumption, and high precision over a wide temperature range. Its advanced features include a current limit of 500mA, an operating junction temperature of -40 °C to +125 °C, and a maximum input voltage of 6V. It has low power dissipation and low-dropout functionality. It is manufactured to be highly reliable and robust under various environmental conditions, making it ideal for applications in telecommunications, automotive, consumer and industrial electronic designs.
