Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LF18CDT is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** Up to 16V  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 1A (max)  
- **Dropout Voltage:** 0.45V (typical at 1A)  
- **Line Regulation:** 0.2mV (typical)  
- **Load Regulation:** 5mV (typical)  
- **Quiescent Current:** 6mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** DPAK (TO-252)  

### **Descriptions:**  
- The LF18CDT is a fixed-output LDO regulator designed for applications requiring stable voltage with low noise.  
- It includes overcurrent and thermal protection.  
- Suitable for automotive, industrial, and consumer electronics.  

### **Features:**  
- Low dropout voltage (0.45V at 1A)  
- High ripple rejection (75dB at 1kHz)  
- Internal current and thermal limiting  
- Fast transient response  
- Compatible with ceramic capacitors  

The information is based on STMicroelectronics' datasheet for the LF18CDT.
