Description and Introduction

18 The TPS3305-33DGNR is a power supply supervisor IC manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V  
- **Number of Outputs:** 1  
- **Reset Threshold Voltage:** Adjustable or fixed (depending on variant)  
- **Reset Timeout Period:** Adjustable or fixed (typically 200ms)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin MSOP (DGNR)  
- **Input Voltage Range:** 1.5V to 10V  
- **Quiescent Current:** Low (typically 35µA)  

### **Descriptions:**
- The TPS3305-33DGNR is a voltage supervisor designed to monitor power supplies in microprocessor and digital systems.  
- It ensures proper system operation by generating a reset signal when the supply voltage falls below a specified threshold.  
- It includes a manual reset input for external control.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Adjustable or Fixed Threshold:** Available in different variants.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Manual Reset Input:** Allows external system reset.  
- **Wide Operating Voltage Range:** Supports various power supply configurations.  
- **Small Package:** 8-Pin MSOP for space-constrained designs.
