Description and Introduction

Micropower 50 mA Ultra Low-Dropout Regulator In SOT-23 and micro SMD Packages The LP2980AIM5-3.2 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (now part of Texas Instruments).  

### **Specifications:**  
- **Output Voltage:** 3.2V (fixed)  
- **Output Current:** 50mA  
- **Dropout Voltage:** 80mV (typical) at 10mA load  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:**  
  - Thermal shutdown  
  - Current limit  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring low quiescent current.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low dropout voltage extends battery life.  
- Suitable for portable electronics, instrumentation, and industrial applications.  
- No external components required for stability (when using recommended capacitors).  
- Reverse-battery protection.  

This regulator is optimized for space-constrained applications due to its small SOT-23-5 package.
