Description and Introduction

Active Low Wide Temperature 3-Pin Reset IC 3-SOT-23 -40 to 105 The LM809M3-4.63/NOPB is a microprocessor reset circuit manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Type:** Voltage Monitor (Microprocessor Reset Circuit)  
- **Reset Threshold Voltage:** 4.63V  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Voltage Range:** 1V to 5.5V  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions and Features:**  
- Provides a reset signal to microprocessors when the supply voltage drops below the threshold.  
- Guaranteed reset output down to VCC = 1V.  
- No external components required.  
- Low quiescent current (typ. 12µA).  
- Immune to short VCC transients.  
- Available in a small SOT-23-3 package.  

This device is commonly used in applications requiring reliable power-on reset functionality, such as embedded systems, automotive electronics, and industrial controls.
