Introduction
The LR8321A series is a high-precision, low-dropout linear regulator based on CMOS technology. It features low quiescent current consumption and high voltage tolerance. The series supports input voltages up to 24 V, with fixed output voltages ranging from 2.5 V to 5 V. The device integrates overcurrent protection to ensure safe operation during use. It can deliver 100 mA of output current under minimal input-output voltage differential while maintaining excellent regulation. The low dropout voltage and low quiescent bias current make these devices particularly suitable for computers, consumer products, and industrial equipment.
Features
- Low input power consumption
- Low input voltage differential
- Input voltage withstand: 24 V
- Low quiescent current: 1.5 μA
- High output accuracy: ±2%
- Integrated short-circuit protection and overcurrent protection
Applications
- Smart lighting devices
- MCU control system power supply
- Dedicated switching power supply auxiliary power
- IoT sensor device power supply
