Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LF90CDT-TR is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics (ST). Below are its key specifications, descriptions, and features based on factual data:  

### **Manufacturer:** STMicroelectronics (ST)  
### **Part Number:** LF90CDT-TR  

### **Specifications:**  
- **Output Voltage:** 9.0V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** Typically 0.45V at 500mA  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.04% (typical)  
- **Load Regulation:** 0.2% (typical)  
- **Quiescent Current:** 5mA (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package:** DPAK (TO-252)  

### **Descriptions:**  
- The LF90CDT-TR is a positive voltage regulator designed for applications requiring stable 9V output.  
- It features low dropout voltage, making it suitable for battery-powered and power-sensitive systems.  
- Includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Short-Circuit Protection:** Safeguards against output short circuits.  
- **Wide Input Voltage Range:** Supports up to 26V input.  
- **Stable with Low ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

This information is derived from STMicroelectronics' official datasheet for the LF90CDT-TR.
