Introduction
The HT73XX series is a CMOS step-down voltage regulator featuring high ripple rejection, low power consumption, and low dropout characteristics, with integrated overcurrent and short-circuit protection. The device offers an ultra-low typical quiescent current of 3.0μA, capable of delivering up to 250mA output current under minimal input-to-output voltage differential while maintaining good voltage regulation. The maximum allowable input voltage is 18V.
Features
- Ultra-low typical quiescent current: 3.0μA
- High output voltage accuracy: ±1% (for 2.8V, 3.3V, 5.0V output voltages); ±2% (for other output voltage values)
- Maximum operating voltage: 18V
- High current capability: output current up to 250mA at 3.3V output voltage
- Ultra-low dropout voltage: 80mV at 40mA output current and 3.3V output voltage
- Low temperature coefficient
Applications
- Cameras and camcorders
- Microprocessor voltage regulators
- LAN card voltage regulators
- Wireless communication devices
- Audio and video equipment
