### **Descriptions:**  
The **LP2980IM5X-4.0** is a low-dropout (LDO) voltage regulator designed for battery-powered and portable applications. It provides a stable 4.0V output with low quiescent current, making it suitable for power-sensitive designs.  

### **Features:**  
- Ultra-low dropout voltage (300mV typical at 50mA)  
- Low quiescent current (75µA typical)  
- Stable with low-ESR ceramic capacitors  
- Thermal shutdown and current limit protection  
- Miniature SOT-23-5 package for space-constrained applications  
- Low output noise (30µVRMS typical)  
- High PSRR (Power Supply Rejection Ratio)  

This regulator is ideal for applications requiring precise voltage regulation with minimal power loss.
