Description and Introduction

Active Low Wide Temperature 3-Pin Reset IC 3-SOT-23 -40 to 105 The LM809M3X-3.08/NOPB is a microprocessor reset circuit manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Reset Threshold Voltage:** 3.08V  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Voltage Range:** 1V to 5V  
- **Reset Timeout Period:** 140ms (minimum)  
- **Quiescent Current:** 17µA (typical)  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +85°C  
- **Accuracy:** ±2.5% (over temperature)  

### **Descriptions and Features:**  
- Monitors system voltage and provides a reset signal to the microprocessor when the voltage drops below the threshold.  
- Active-low reset output ensures proper system initialization.  
- Low power consumption for battery-powered applications.  
- No external components required for operation.  
- Immune to short voltage transients.  
- Suitable for 3.3V and 5V systems.  
- Lead-free and RoHS compliant.  

This device is commonly used in embedded systems, industrial controls, and automotive applications where reliable voltage monitoring is critical.
