Overview
Description
The HT7533-2 is a low-dropout (LDO) voltage regulator from Holtek, providing a fixed 3.3V output with a 100mA current capacity. It features a low quiescent current (~4µA) and a dropout voltage as low as 100mV, making it suitable for battery-powered applications.
Key characteristics:
- Input voltage range: 4V to 12V
- Output voltage: 3.3V (±2% accuracy)
- Low power consumption: Ideal for portable devices
- Package options: TO-92, SOT-89
Applications include powering microcontrollers, sensors, and other low-power electronics in devices like IoT nodes, wearables, and consumer electronics. The "-2" suffix indicates a tighter voltage tolerance compared to standard variants.
For stable operation, a small output capacitor (≥1µF) is recommended. Always refer to the datasheet for detailed specifications.
