Description and Introduction

Active Low Wide Temperature 3-Pin Reset IC 3-SOT-23 -40 to 105 The LM809M3-3.08/NOPB is a microprocessor reset circuit manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Type:** Voltage Monitor (Reset IC)  
- **Reset Threshold Voltage:** 3.08V  
- **Output Type:** Active-Low, Push-Pull  
- **Operating Voltage Range:** 1V to 5V  
- **Reset Timeout Period:** 140ms (min)  
- **Package:** SOT-23-3  
- **Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LM809M3-3.08/NOPB is designed to monitor system voltages and provide a reset signal to microprocessors or microcontrollers when the supply voltage falls below the preset threshold (3.08V). It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- Precise voltage monitoring (3.08V threshold)  
- Low quiescent current (5µA typical)  
- No external components required  
- Push-pull output (no pull-up resistor needed)  
- Guaranteed reset output valid down to VCC = 1V  
- Small SOT-23-3 package  

This device is commonly used in embedded systems, industrial controls, and automotive applications.
