Description and Introduction

Active Low Wide Temperature 3-Pin Reset IC 3-SOT-23 -40 to 105 The **LM809M3X-2.93 NOPB** is a microprocessor reset circuit manufactured by **National Semiconductor (NSC)**.  

### **Specifications:**  
- **Type:** Voltage Monitor / Reset IC  
- **Reset Threshold Voltage:** 2.93V (fixed)  
- **Output Type:** Active-Low, Open-Drain  
- **Operating Voltage Range:** 1V to 5V  
- **Reset Timeout Period:** 140ms (typical)  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5µA (typical)  

### **Descriptions:**  
- The LM809M3X-2.93 is designed to monitor power supply voltages in microprocessor and digital systems.  
- It asserts a reset signal when the supply voltage drops below the 2.93V threshold, ensuring proper system initialization.  
- The open-drain output allows flexibility in interfacing with different logic levels.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset triggering at 2.93V.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Small Form Factor:** SOT-23-3 package saves board space.  
- **No External Components Required:** Simplifies circuit design.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

This device is commonly used in embedded systems, automotive electronics, and industrial control applications where reliable power-on reset functionality is critical.
