HT7533-2 Description

Short technical summary and product information.

The HT7533-2 from HOLTEK is a three-terminal low power, high voltage LDO voltage regulator implemented in CMOS technology. It provides a stable 3.3V output voltage with an accuracy of ±1% and can deliver up to 100mA of output current. The device accepts an input voltage as high as 24V, making it suitable for a wide range of applications.

Key features include low power consumption, a low voltage drop, and a low temperature coefficient. The HT7533-2 is available in a SOT-89 package, designed for surface mounting. Its low quiescent current and high input voltage capability make it an ideal choice for battery-powered equipment, communication devices, and audio/video applications where power efficiency and stable voltage regulation are critical.

While primarily designed as a fixed voltage regulator, the HT75XX-2 series can be used with external components to achieve variable voltages and currents. This flexibility, combined with its compact package and robust performance, makes the HT7533-2 a versatile component for power management in various electronic designs.
