Description and Introduction

Micropower Precision Triple Supply Monitors in 8-Lead MSOP and 5-Lead SOT-23 Packages The **LTC1728ES5-3.3#TRMPBF** is a microprocessor supervisory circuit manufactured by **Linear Technology (now part of Analog Devices)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Supply Current:** 6µA (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** Adjustable (default: 140ms)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LTC1728 is a low-power supervisory circuit designed to monitor system voltages in microprocessor-based applications.  
- It provides a reset signal to the microprocessor when the supply voltage drops below a preset threshold, ensuring proper system initialization.  
- The device features an adjustable reset timeout period and operates with very low quiescent current, making it suitable for battery-powered applications.  

### **Features:**
- **Low Power Consumption:** Only 6µA typical supply current.  
- **Precision Voltage Monitoring:** ±1.5% reset threshold accuracy.  
- **Wide Operating Voltage Range:** 1.2V to 5.5V.  
- **Adjustable Reset Timeout:** Can be set via an external capacitor.  
- **Small Package:** SOT-23-5 for space-constrained applications.  
- **Manual Reset Capability:** Supports an external pushbutton reset input.  

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