Description and Introduction

Micropower 50 mA Ultra Low-Dropout Regulator In SOT-23 and micro SMD Packages The LP2980IM5-2.9 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 2.9V (fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 300mV (typical at 100mA load)  
- **Input Voltage Range:** 2.3V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Accuracy:** ±2% over line, load, and temperature  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  

### **Features:**  
- **Ultra-Low Dropout:** Ensures stable output even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Thermal & Current Limit Protection:** Prevents damage from overheating and overcurrent.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Enable Pin (SOT-23-5 Package):** Allows shutdown mode for power savings.  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- Noise-sensitive analog circuits  
- Post-regulation for switching supplies  

This regulator is designed for efficiency and reliability in space-constrained applications.
