Description and Introduction

Micropower, 300mA Ultra Low-Dropout CMOS Voltage Regulator The LP3981ILDX-2.83 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Output Voltage:** 2.83V (fixed)  
- **Output Current:** 300mA  
- **Dropout Voltage:** 120mV (typical at 100mA load)  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Low Quiescent Current:** 75µA (typical)  
- **High PSRR:** 70dB at 1kHz  
- **Package:** 6-pin WSON (2mm x 2mm)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions and Features:**  
- Ultra-low dropout voltage for extended battery life in portable applications.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- High power supply ripple rejection (PSRR) for noise-sensitive applications.  
- Fast transient response for dynamic load conditions.  
- Designed for space-constrained applications due to its small WSON package.  
- Suitable for powering microcontrollers, RF modules, and other low-voltage devices.  

This regulator is optimized for efficiency and reliability in battery-powered and noise-sensitive systems.
