  - Current limit  

### **Descriptions:**  
The LP2980AIM5X-4.5 is a precision, low-dropout regulator designed for battery-powered applications. It provides a stable 4.5V output with low noise and high power supply rejection ratio (PSRR), making it suitable for noise-sensitive circuits.  

### **Features:**  
- Ultra-low dropout voltage (300mV typical at full load)  
- Low quiescent current (75µA typical)  
- Stable with low-ESR ceramic capacitors  
- Thermal shutdown and current limit protection  
- High accuracy (±1% over line, load, and temperature)  
- Small SOT-23-5 package for space-constrained designs  

This regulator is commonly used in portable electronics, battery-powered devices, and noise-sensitive applications.
