Description and Introduction

3/4 Pin 500mA Fixed 3.3V Positive Voltage Regulator 3-TO-220 0 to 125 The UA78M33CKCSE3 is a positive voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** +3.3V (fixed)  
- **Output Current:** Up to 500mA  
- **Input Voltage Range:** Up to 35V  
- **Dropout Voltage:** 2V (typical)  
- **Line Regulation:** 0.03%/V (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package:** TO-220 (KCS)  

### **Descriptions:**
- The UA78M33CKCSE3 is a linear regulator designed to provide a stable +3.3V output from a higher input voltage.  
- It includes internal current limiting, thermal shutdown, and safe operating area (SOA) protection.  
- Suitable for a wide range of applications, including industrial, automotive, and consumer electronics.  

### **Features:**
- **Fixed Output Voltage:** 3.3V with high accuracy (±2%).  
- **Thermal Protection:** Built-in thermal shutdown prevents damage from overheating.  
- **Short-Circuit Protection:** Internal current limiting safeguards against excessive current.  
- **Low Noise Output:** Provides stable DC voltage with minimal ripple.  
- **Wide Input Voltage Range:** Supports up to 35V input.  
- **TO-220 Package:** Allows for easy heat dissipation with an optional heatsink.  

This regulator is commonly used in power supply circuits requiring a reliable +3.3V output.
