Description and Introduction

Lithium Battery Protection Circuit for One Cell Battery Packs The MC33349N-3R1 is a voltage regulator manufactured by ON Semiconductor. Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage:** 3.1V (fixed)  
- **Output Current:** Up to 50mA  
- **Dropout Voltage:** Typically 0.5V at 50mA  
- **Quiescent Current:** Typically 1.5mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TO-92 (3-pin)  

### **Descriptions:**  
- The MC33349N-3R1 is a low-dropout (LDO) linear voltage regulator designed for low-power applications.  
- It provides a fixed 3.1V output with stable performance over varying input voltages.  
- Suitable for battery-powered devices, automotive systems, and industrial controls.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage due to overheating.  
- **Short-Circuit Protection:** Safeguards the regulator from output short circuits.  
- **Wide Input Voltage Range:** Supports operation from 4.5V up to 40V.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  

This information is based on ON Semiconductor's datasheet for the MC33349N-3R1.
