Description and Introduction

Power Sequencer The LM3880MF-1AE is a power sequencing and monitoring IC manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Key Specifications:**  
- **Manufacturer:** Texas Instruments (formerly National Semiconductor)  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable (200ms typical)  
- **Quiescent Current:** 8µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The LM3880MF-1AE is a simple, low-power voltage supervisor with an adjustable reset timeout. It monitors a power supply voltage and asserts a reset signal when the voltage falls below a preset threshold. It is commonly used in microprocessor and microcontroller applications to ensure proper power-up and power-down sequencing.  

### **Features:**  
- Adjustable reset timeout via an external capacitor  
- Low quiescent current (8µA typical)  
- Wide operating voltage range (1.6V to 5.5V)  
- Precision voltage monitoring (±1.5% threshold accuracy)  
- Small SOT-23-5 package for space-constrained designs  
- No external resistors required for threshold setting  

This device ensures reliable system operation by preventing erratic behavior during power transitions.
